Bugs are one of my favourite costume families to sew, because almost every one of them is a plain coloured base plus two or three added details: wings, a shell, extra legs or antennae. That makes them cheap to build and easy to scale from a toddler to an adult. Below you'll find the obvious bees and butterflies alongside beetles, cicadas, moths and a walking leaf, each with the clothing, body details, hair, makeup and shoes it needs. Most can be made from closet pieces, felt, cardboard and fabric paint. I've noted where a shape tends to fail and what I'd change, and the last few ideas cover couples and groups.
Building Wings That Hold Their Shape All Night
Most of these costumes have wings, and most homemade wings fail in the same two ways: they droop by the second hour, or they swing sideways and hit the person next to you. Both problems come from how they're framed and strapped, not from the fabric on top.
- Bend the frame from wire that holds a curve when you press on it. Two shapes per side, twisted together where they meet the back, is stronger than one big loop.
- Cover the frame with something light: sheer fabric, mesh, an old pair of tights stretched over and knotted, or felt for the solid-coloured bugs.
- Fix both wings to a small back plate, a rectangle of cardboard wrapped in felt. That plate takes the strain instead of the fabric of your top.
- Run elastic from the plate over each shoulder and cross it at the front of the chest, like a backpack with the straps crossed. Uncrossed straps slip off the shoulders.
- Check the span in a doorway before you finish. If you have to turn sideways to get through, trim them now.
For antennae, plain pipe cleaners flop within an hour. I twist each one around a length of thin floral wire first, then wrap the base tightly onto the headband with tape so it can't spin. Pom-poms on the tips look cute but add weight, so keep them small.
1. Classic Ladybug Costume
The ladybug is the one I'd hand to a first-time costume maker. A red dress, a red sweatshirt with leggings, or a red tee over a black skirt all make the base, and round black felt spots go on with safety pins, fabric tape or removable adhesive. Felt or cardboard wings with a black line down the centre sit on the back. I cut the spots in three sizes rather than one, because evenly sized dots look printed and slightly flat. Black tights, ankle boots, a black headband with pipe-cleaner antennae, a ponytail or bun, black liner, rosy cheeks and a red lip finish it, and a small flower or leaf in hand tells people it's a garden bug.
2. Bumblebee Costume
Stripes do all the work on a bumblebee, so get them right first. A striped sweater is easiest; on a plain yellow top I lay horizontal strips of black felt and keep them a little wider than looks right on the table, since thin stripes blur into grey from a distance. Black leggings, a skater skirt or joggers go underneath. Sheer rounded wings on elastic shoulder straps and a headband with curved black antennae come next. Yellow ribbons or temporary colour pull the palette into the hair, and gold eyeshadow, black liner and a yellow dot on each cheek keep the face playful. Black sneakers make it walkable, and a felt flower or a small bucket labelled “honey” is the prop.
3. Monarch Butterfly Costume
Monarch wings are the whole costume, so build them big and attach them at the shoulders and the wrists. That second anchor point is what makes them open like a real butterfly every time the arms lift. Under them, a fitted black top with leggings, trousers or a simple dress keeps the outline clean. I paint the orange sections on lightweight fabric or felt, add the black borders and finish with small white dots along the edges, which is the detail people actually recognise. Black flats, a sleek bun with orange clips, curled antennae, orange shadow, winged liner and tiny white face-paint dots by the eyes complete it. Carry a bright fabric flower and stand with the wings fully spread for photos.
4. Blue Butterfly Costume
A blue butterfly is a calmer version of the monarch and easier to wear to a grown-up party. Start with a royal blue dress, a blue jumpsuit, or a matching top and skirt over black tights. The wings mix turquoise, navy and black; translucent fabric keeps them light, while painted poster board holds a sharper edge but creases if you lean back in a chair. Black flats, sneakers or short boots echo the dark wing borders. Loose waves with blue clips or a shoulder-length blue wig suit it, with silver-blue shadow, fine black liner and a few dots at the temples. A black antenna headband and a felt or paper flower wand finish it.
5. Luna Moth Costume
Luna moths have long trailing points on the lower wings, and that tail is what separates this from a green butterfly. Keep it. A pale green maxi dress, a matching shirt and trousers, or a green tunic over leggings sets the colour. Cut wide mint wings with subtle circular markings, and use soft fabric here rather than card, because it sways as you walk. Cream flats or pale sneakers, loose waves or a mint wig, shimmery green shadow, pearly highlight and fine white dots suit the soft palette. Feathery antennae and a small moon-shaped bag or silver star are the finishing details.
6. Fuzzy Brown Moth Costume
This is the bug I'd pick for a cold night outdoors. The base is a tan fleece, a brown sweater dress or an oversized cardigan over matching leggings, so you're warm before you even add the wings. Make those from felt or brushed fabric in brown, cream, grey and rust, with a few simple lines suggesting the markings; too many lines and it starts to look like camouflage. Brown boots or cushioned sneakers, tousled hair or two fluffy space buns, bronze shadow and soft brown liner go with it. Thick feathery antennae, fingerless gloves and a lightweight paper lantern, the light every moth heads for, make the joke land.
7. Green Dragonfly Costume
Dragonflies are long and narrow, so the costume should be too. A metallic green top with black leggings, fitted trousers or a green unitard (layered for the event) gives the sleek line. Two pairs of slim translucent wings go on with elastic straps or a small backpack-style harness, and I draw the veins with silver or black fabric paint before attaching them, while the wing is flat. Green sneakers or flat boots, a high ponytail with green extensions or metallic ribbon, emerald shadow, silver liner and bright cheekbones finish the body. Lightweight round sunglasses make the big eyes. Skip props entirely; the wings need your hands free to stay out of trouble.
8. Blue Damselfly Costume
A damselfly is the dragonfly's slimmer cousin, and building it teaches you a lot about wire. Wear a turquoise fitted top with navy pants, leggings or a straight midi skirt. The four slim wings are transparent vinyl, sheer fabric or white mesh stretched over flexible wire, with pale blue lines for structure. Bend the wire ends back into small loops before covering them so nothing pokes through. Navy sneakers or low boots, a smooth braid with blue ribbon, turquoise shadow, precise navy liner and a touch of silver highlight go with it. Small antennae and round blue glasses make the face. A segmented fabric belt that trails slightly behind the waist suggests the long body without catching on chairs.
9. Glowing Firefly Costume
Fireflies need a real glow, and battery-powered lights are the only safe way to get it. Start all black: a sweatshirt and leggings, a jumpsuit, or a long-sleeve dress with tights. Short translucent wings outlined in silver fabric tape sit on top. The light goes in a yellow fabric pouch at the lower back, and I sew a small opening into the pouch so the battery pack can be switched on and off without undressing. Black sneakers or boots, a sleek ponytail or two compact buns under curved antennae, and gold shadow with yellow at the outer corners finish it. A clear jar filled with battery fairy lights adds a second glow that's fine for kids.
10. Rainbow Beetle Costume
Iridescent fabric does most of the work on a rainbow beetle. A metallic bodysuit (layered as needed), a shiny blouse and trousers, or a colour-shifting dress over opaque tights forms the base. The shell is a rounded cape of cardboard, foam or quilted fabric in purple, teal, blue and green, with a line down the centre for the two wing covers. Quilted fabric is my pick here: it holds a curve, folds into a bag and won't crack when you sit. Black platform sneakers or ankle boots, a high bun with metallic clips, multicolour shadow, glossy highlight and graphic liner suit the brightness. Curved antennae, fingerless gloves and round tinted glasses for beetle eyes finish it.
11. Green June Beetle Costume
June beetles are deep green with a bronze sheen, and the trick is keeping the shell light. Choose an emerald jumpsuit, a green dress, or a satin top with matching trousers. A rounded metallic green cape forms the shell, with a narrow bronze stripe down the middle. I line that cape with a thin layer of batting instead of cardboard so it keeps the domed look but still lets you sit in a booth. Black or bronze boots, a low bun or a short dark-green wig, emerald shadow, bronze liner and a little shimmer on the cheekbones go with it. Short curved antennae, dark gloves and a small fabric leaf complete it.
12. Stag Beetle Costume
Stag beetles are all about the jaws, but hard pincers on a headband are a poke waiting to happen. Make two short curved shapes from padded foam instead, and keep them light so the headband doesn't slide forward. The body is a black hoodie, a black jumpsuit, or a long-sleeve top and pants under a rounded foam or cardboard shell with brown highlights for depth. Black gloves and chunky sneakers keep the monochrome running head to toe. Slick the hair back or tuck it into a black beanie before the headpiece goes on. Smoky brown shadow, clean liner, a little contour and a cardboard log or felt leaf keep it in the woods rather than the haunted house.
13. Scarab Beetle Costume
A scarab mixes beetle shape with jewel tones and gold. Wear a turquoise tunic, a metallic green dress, or a blue top with gold-trimmed trousers. The rounded wing cape is teal and navy, decorated with symmetrical gold fabric-paint lines, and a wide gold belt marks the segmented middle. Symmetry matters more on this one than any other bug here, so I mark a centre line in chalk and paint both sides together, a little at a time. Metallic flats or ankle boots, a smooth bob or braided updo with turquoise and gold accessories, deep blue shadow and gold liner suit it. Short black antennae, gold cuffs and a painted cardboard sun disk finish the costume.
14. Rhinoceros Beetle Costume
Rhinoceros beetles look heavy, but nothing about the costume should be. A dark brown sweatshirt and trousers, a black jumpsuit or layered thermals for outdoors make the base, under a large rounded shell of foam, fabric or painted cardboard in black or deep chestnut. The horn is the signature, and I make it from stuffed felt, sewn onto a hood rather than a headband, because a hood spreads the weight and doesn't tip. Brown work-style boots or black sneakers, short or slicked-back hair, dark brown shadow and bold brows go with it. Black gloves and a foam tree-bark shield finish it without anything sharp.
15. Praying Mantis Costume
The folded front arms are what make a praying mantis, and they have to leave the hands free. I attach soft foam panels along the forearms with elastic loops at the wrist and elbow, so you can still hold a drink. The rest is a green hoodie, jumpsuit, or long-sleeve top and leggings, with small leaf-shaped wings on the back and green sneakers or flexible boots. A high braided ponytail, a green bob wig or a smooth bun sits under long curved antennae. Lime shadow, sharp green liner and highlighted cheekbones give the face an angular finish, and round green glasses make the eyes. Practise the folded-arm pose; it explains the costume in one second.
16. Flower Mantis Costume
Flower mantises are pink and white and shaped like petals, which turns the mantis idea into something soft. Wear a pale pink dress, a soft jumpsuit or a petal-shaped tunic over white leggings. Layer fabric petals at the shoulders and hips, and add short cream wings across the back. The forearm panels are the same as the green mantis, just in pink foam. Petals cut from a fabric that doesn't fray, like felt or a bonded knit, save you hemming dozens of edges. White sneakers or pink flats, a curled updo with silk flowers, rosy shadow, white liner and small petal details at the temples go with it. Slender antennae and a lightweight flower stem finish it.
17. Green Grasshopper Costume
Grasshoppers suit kids and anyone who won't stay still. A bright green sweatshirt with matching joggers or leggings is the base, with a lighter green belly panel and small brown or yellow wings on the back. The jumping legs are padded felt shapes attached to the sides of the pants. Stitch them at the top only, not along the whole leg, or they pull the trousers tight every time the knee bends. Green sneakers, a green hood or high ponytail under curved antennae, lime shadow, rosy cheeks and a thin smile line keep it friendly. Rounded glasses make the big eyes, a felt blade of grass is the prop, and a bent-knee pose sells it in photos.
18. Black Cricket Costume
If your closet is mostly black, you're two steps from a cricket. A black turtleneck or sweatshirt with fitted pants, leggings, or a midi skirt and tights makes the base. Short brown-black wings go on the upper back, with slim padded leg panels near the thighs. Black sneakers or lace-up boots keep it practical. A low ponytail, a smooth bun or a short black wig all suit it. With an all-dark palette, the face disappears in photos, so I add a little silver highlight next to the charcoal shadow and black liner. Long curved antennae are essential, and a cardboard music note or a toy-size felt violin nods to the chirping.
19. Red Ant Costume
A red ant is bright enough for a party and built from very basic pieces. A red long-sleeve top with red leggings, joggers or a jumpsuit is the body, and two rounded fabric sections at the back of the waist give the segmented shape. The extra pair of stuffed felt arms is the funny part; I attach them at the shoulder seam and let them hang loose so they flop as you move. Red sneakers or black boots, three small buns or a red bob wig under bent antennae, warm red shadow, black liner and dotted cheeks go with it. An oversized cardboard crumb or felt picnic item tells everyone what this ant was after.
20. Black Ant Costume
The black ant is the version I'd suggest for a group, since everyone can make the same base and then personalise it. A black long-sleeve shirt and leggings, a jumpsuit, or a sweatshirt and comfortable pants is the start. Three rounded segments of stuffed black fabric run vertically down the back, with a second pair of light felt arms below the real ones. Stuff those segments loosely; packed hard, they push you forward off the back of a chair. Black gloves, cushioned sneakers, a sleek bun or fitted black cap, graphite shadow, defined brows and a little silver near the eyes finish it. Curved antennae and a foam sugar cube, leaf or picnic crumb add the joke.
21. Queen Ant Costume
Wings separate the queen from her workers, so they're not optional here. Wear a black maxi dress, a tailored jumpsuit or a long tunic over leggings, with a segmented black bustle at the back and translucent grey wings. Black flats or low boots keep you steady. A smooth updo carries a lightweight silver crown, which I wire to the same headband as the antennae so the two don't fight for space. Smoky eyes, silver liner and a berry lip suit the royal tone. Black gloves and a small silver sceptre topped with a foam sugar cube finish the look, which is dramatic but easy to wear for hours.
22. Colorful Caterpillar Costume
Caterpillars are round and soft, which is exactly why little kids like wearing them. Put on a green sweatshirt and matching leggings, then attach stuffed fabric circles in blue, yellow, red or purple down the back. A striped tunic gives the same segmented effect with less bulk, and it's the better choice for car seats. Add small felt legs along the sides and colourful sneakers for walking. Pigtails, a green wig or a ponytail threaded with ribbon, pastel shadow, rosy cheeks and tiny dots around the eyes go with it. Short antennae and a big felt leaf with pretend bite marks finish it, and every piece stays soft enough for a parade or classroom.
23. Woolly Bear Caterpillar Costume
Woolly bears are black at both ends with a rust band in the middle, and that band is the whole identification. A fuzzy black sweater or fleece with black leggings is the base, and a wide rust-orange band of felt, fabric or a removable sash goes around the middle. Small soft legs run along both sides of the torso. Keep them short; long dangling legs catch on door handles and car doors. Black boots or sneakers, a tousled bob, two fluffy buns or a black knit cap with short antennae, copper shadow, black liner and peach blush suit it. A large brown felt leaf brings in the October woods.
24. Garden Snail Costume
A snail isn't an insect, but it belongs in any garden-bug lineup. Wear a sage green sweatshirt dress, brown overalls over a green top, or an earth-toned jumpsuit. The shell is coiled brown foam, painted cardboard or a rolled fabric tube on backpack straps. I'd go with the fabric tube for anyone sitting down a lot: it squashes and springs back where cardboard dents. A headband carries two long eye stalks and two shorter feelers. Brown boots or green sneakers, a low bun or loose waves, fresh green shadow, soft brown liner and rosy cheeks go with it, and a felt lettuce leaf or a “slow and steady” sign gives it a gentle joke.
25. Silver Pill Bug Costume
Pill bugs are armour, so the costume is all about overlapping panels that still let you bend. Begin with a charcoal sweatshirt and black leggings, joggers or a fitted jumpsuit. Curved grey foam panels run down the back, each overlapping the next. Attach every panel only along its top edge, like roof shingles, so they slide over each other when you sit. Paint them metallic silver or add reflective tape. Black sneakers or grey ankle boots, hair tucked into a charcoal hood or a short silver wig, silver shadow, dark liner, short antennae and grey gloves finish it. A curled crouch and a fabric leaf make the idea obvious.
26. Housefly Costume
Played for laughs, a housefly is far more fun than creepy. Wear a grey sweatshirt, a black shirt and pants, or a charcoal tunic with black leggings. Two translucent wings with visible black vein lines go on the back. The compound eyes are oversized round glasses, and that one accessory is what people read first, so pick the biggest pair you can see through. Short antennae sit above them. Black sneakers or grey boots, a tight bun or a short grey wig, silver-grey shadow, black liner and tiny dots at the temples finish the face. An extra pair of soft felt arms and an oversized foam sugar cube or picnic plate push the cartoon side.
27. Fruit Fly Costume
Fruit flies have red eyes, and that's the detail that turns a tiny household bug into a party costume. Oversized red glasses do it. Start with a brown or black shirt and matching leggings, trousers or overalls, then add clear rounded wings and short antennae. Black sneakers or brown boots, a short bob, messy bun or low ponytail, reddish shadow at the outer corners, neat liner and peach blush complete it. Carry a big lightweight piece of felt fruit, an apple slice or banana, and pin a few fabric leaves to the costume. On a dark base, that bright prop is what keeps the photo interesting.
28. Cicada Costume
Cicadas have long clear wings with strong veining, and painting those veins is the part worth slowing down for. Lay the wing film flat on paper, sketch the pattern in pencil underneath, and trace it in brown, gold or green paint. Wear a black or dark green top with matching pants, leggings or a jumpsuit, with a bronze segmented panel down the torso. Brown boots or dark sneakers, a braided bun with metallic green clips or a short bronze wig, moss-green shadow, bronze liner and shimmer at the temples go with it. Short antennae and round tinted glasses make the eyes, and a cardboard branch or faux leaves on a wrist cuff finish it.
29. Spotted Lanternfly Costume
Spotted lanternflies have two wing layers: pale grey with black spots on top, bright red with graphic black marks underneath. To show both, I cut the red lower wings slightly longer than the grey ones, so they peek out below. Wear a black top with leggings, trousers, or a knee-length dress over tights. Keep the wings light and attach them at the shoulders and wrists so you can open them when someone asks what you are. Red sneakers or black ankle boots, a sleek black ponytail with red extensions, red and grey shadow, winged liner and small face-paint dots near the temples suit it. Short antennae and a fabric tree leaf finish it.
30. Green Lacewing Costume
Green lacewings are delicate and pale, so this one suits a bright party better than a dark night. Wear a light green dress, a mint jumpsuit or a lime sweater with matching leggings. Four clear mesh wings carry fine green veins, and the frame should stay narrow and flexible; wide lacewing wings on a stiff frame snap the first time they hit a door frame. White sneakers or mint flats, a loose braid with green ribbon or a pale green wig, mint shadow, fine green liner and pearly highlight keep the palette light. Slender antennae, translucent gloves and a small white flower or leafy wand finish it without hiding the lace.
31. Walking Leaf Costume
This costume is all about camouflage, and the more leaf shades you use, the better it works. Start with a moss-coloured hoodie, tunic or jumpsuit over matching leggings. Large fabric leaves go along the sleeves, shoulders and back, placed so every joint can still bend, plus a short leaf-shaped cape with brown vein lines. I mix three or four greens; a single shade reads as a green blob in photos. Green sneakers or brown boots, a messy braid with faux foliage or a textured green wig, olive shadow, brown liner and fine leaf lines at the temples go with it. Long thin antennae and a light twig finish the illusion.
32. Walking Stick Costume
Walking sticks are long straight lines, which makes them one of the easiest builds here. Wear a brown fitted top with straight-leg pants, leggings or a jumpsuit. Narrow fabric-covered foam extensions run along the outer arms and legs; keep them short and flexible, and stop the leg pieces well above the ankle or you'll step on them on stairs. Brown sneakers or boots blend into the base. A long braid, a brown hood or a straight dark wig, matte brown shadow, defined brows and soft branch lines on the cheeks suit it. Two thin antennae and a light cardboard-and-felt branch with no pointed ends finish it.
33. Cute Spider Costume
Eight limbs can look scary or silly, and soft, stuffed ones land firmly on silly. Wear a black hoodie with black leggings, joggers, or a dress and tights, then attach three extra pairs of stuffed fabric arms down the sides. I connect them to each other at the wrists with a loose thread so they swing together instead of tangling. Purple, pink or silver accents keep it playful. Black sneakers or colourful boots, space buns under a headband of soft craft eyes, purple shadow, graphic liner and tiny dots around the temples go with it. A white yarn web stretched in an embroidery hoop is the prop. Leave out fangs and gory makeup so smaller kids aren't spooked.
34. Lovebug Couple Costume
Lovebugs are an easy couple costume because the pair doesn't need identical clothes, only the same colours. One person might wear a red dress with black tights and the other a red shirt with black trousers. Both get matching spotted wings, curved antennae and comfortable black shoes. The fun detail is a lightweight foam heart cut in half, one half each, that only completes when you stand together. Cut the heart first and then size the wing spots to match its curve; heart-shaped spots tie it together. Red clips or ribbons, rosy cheeks, black liner and subtle red accents suit each wearer. It works as well for best friends, siblings or a parent and child.
35. Bug Swarm Group Costume
A swarm lets everyone in a group pick their own bug while still looking like one team. Assign the characters, say a bee, ladybug, butterfly, beetle, moth, ant, dragonfly and caterpillar, and give each person a colour-matched base, wings or body panels, antennae, simple makeup and comfortable shoes. Then repeat one shared detail across everyone, like matching black antenna headbands or the same green leaf prop; that repeat is what makes strangers see a group instead of eight separate costumes. Hair can vary to suit each bug. In photos, put the people with the biggest wings at the back so nobody vanishes. It suits friends, families, classrooms or coworkers of mixed ages.
Felt, Paint or Tape: What Actually Stays On
Spots, stripes and markings are where bug costumes start peeling. The fixing method has to suit both the fabric underneath and whether you want to wear the clothes again afterwards.
- Safety pins are the honest choice for borrowed or everyday clothes. Pin from the inside so the head doesn't show, and use at least two per spot so they don't spin.
- Fabric glue and hot glue hold well on cotton and felt, but they often let go on slippery polyester and stretch knits, and hot glue turns brittle on a cold night.
- Iron-on adhesive behind felt shapes lasts the longest on cotton sweatshirts. It's permanent, so only use it on clothes you're happy to keep as a costume.
- Fabric paint is best for fine lines like wing veins. Let it dry flat and fully before folding, or it prints onto the opposite side.
- Double-sided fabric tape is fine for a few hours of photos indoors but tends to lift once you start moving and warming up.
Which Bugs Cope With Trick-or-Treating
Before you commit, think about where the costume is going. Big wings and rigid shells are lovely at a party, but they're hard work in a car, on a crowded sidewalk or through front doors all evening.
For a long walk outside, I'd lean toward the bugs that live in their clothing: the bee, ladybug, ants, woolly bear, cricket, grasshopper and caterpillar. Their details are flat or soft and sit close to the body, and you can wear a warm layer underneath without changing the look. The monarch, lanternfly, dragonfly and lacewing are better saved for indoor events, or built with smaller wings for the walk. For small children, make the antennae from fabric rather than wire, keep every prop soft, and add a strip of reflective tape to the back plate so drivers can see them after dark.
Start With Antennae and One Good Pair of Wings
Every bug in this list comes down to a recognisable colour and a few added shapes, worn over clothes you can move and sit in. Start with a breathable base, keep the wings and shell light, and make the antennae soft enough that a hug doesn't bend them. Felt, cardboard, foam, thrifted clothing and removable fabric tape will cover most of these builds, from the simple ladybug and bee to the cicada, lacewing and walking leaf. Nearly all of them scale down for children or up for couples and groups. Pick the bug whose details you'd enjoy making, and match your shoes to how far you'll actually walk.
