Moth
A broad group of scale-winged insects related to butterflies, typically nocturnal, with stout, often furry bodies and feathery or thread-like antennae.
moth
Small Emperor Moth
A striking day-flying moth with large eyespots on all four wings, gray-brown coloring in males and paler gray in the larger females, native to heathlands and open countryside across Europe.
moth
Gypsy Moth (Spongy Moth)
A strongly sexually dimorphic moth, recently renamed the Spongy Moth for its distinctive spongy, tan egg masses, whose caterpillars are known for periodically defoliating oak and other hardwood trees in large outbreak years.
moth
Winter Moth
A small tan-brown moth unusual for flying in the cold of late autumn and early winter, with strongly dimorphic sexes: fully winged males and flightless, near-wingless females that climb tree trunks to lay eggs.
moth
Emperor Moth
A striking silk moth with a large eyespot on each of its four wings, showing pronounced differences between the smaller, orange-brown, day-flying males and the larger, greyer, night-flying females.
moth
Luna Moth
A large, pale lime-green silk moth with long, elegant tails trailing from its hindwings, considered one of the most striking nocturnal insects in North America.
moth
Clothes Moth
A tiny, pale golden moth that avoids light and flutters weakly from dark closets, more often noticed by the damage its larvae leave in stored fabrics than by the moth itself.
moth
Promethea Moth
A medium-sized silk moth showing striking differences between the sexes, with dark, blackish-maroon males that mimic a distasteful swallowtail butterfly in flight and larger, more colorful reddish-brown females marked with pale borders and eyespots.
moth
Codling Moth
A small, inconspicuous grey-brown moth best known through the work of its larva, the classic apple 'worm' that tunnels into fruit, making this tiny moth one of the most economically significant insects in orchards worldwide.
moth
Drinker Moth
A stout, furry moth with warm tawny-orange to buff-brown wings marked by two small white spots on each forewing, named for its caterpillar's habit of drinking water droplets from grass blades.
moth
Hummingbird Moth
Hovering at flowers with a blur of wings and a long uncoiling tongue, the hummingbird moth is easily mistaken for a tiny hummingbird. These plump, fast-flying hawk moths feed on nectar in broad daylight.
moth
Wax Moth
A plain grey-brown moth whose larvae tunnel through beeswax honeycomb, spinning silk webbing as they feed, making it a well-known pest of beekeeping operations.
moth
Plume Moth
A slender, long-legged moth that rests with its wings rolled tightly and held out at right angles to its body, forming a distinctive letter-T silhouette.
moth
Lappet Moth
A large, richly textured moth with deeply scalloped, russet-brown wings that fold into an uncanny dead-leaf silhouette, one of the most convincing leaf mimics among European moths.
moth
Tussock Moth
A moth with a striking split lifestyle: winged, drab gray-brown males fly to seek out flightless, grub-like females, while the ornate caterpillars sport dense tufts of colorful bristly hair.
moth
Bagworm Moth
A moth best known for its larva's habit of constructing and living inside a spindle-shaped case of silk and plant debris that hangs from twigs, with adult males a plain sooty-winged moth and females remaining wingless and grub-like inside the bag for life.
moth
Grain Moth
A tiny buff-colored moth whose larvae tunnel invisibly inside individual kernels of stored grain, hollowing them out from within.
moth
Polyphemus Moth
A large tan-to-golden-brown silkmoth named for the mythological one-eyed giant, thanks to the single large, transparent eyespot on each hindwing that flashes into view when the moth is startled.
moth
Comet Moth (Madagascan Moon Moth)
One of the largest and most spectacular silk moths in the world, with pale yellow-to-red wings and extraordinarily long, ribbon-like tails on the hindwings.
moth
Diamondback Moth
A small, slender grey-brown moth named for the pale, diamond-shaped pattern that appears down its back when the wings are folded, best known as a widespread pest of cabbage and other brassica crops.
moth
Fox Moth
A stout, reddish-brown moth with a pale diagonal band across each forewing, closely resembling a fox in color, most often noticed as its large, densely furred dark caterpillar basking on open ground in spring.
moth
Gypsy Moth Caterpillar (Spongy Moth)
A bristly, blue-and-red-spotted caterpillar that can strip entire hardwood forests bare during major outbreak years.
caterpillar-larva
Indianmeal Moth
A small moth with two-toned, coppery-and-gray wings whose caterpillars spin silken webbing through stored grain, cereal, and dried fruit.
moth
Vapourer Moth
A small tussock moth with striking sexual dimorphism: rusty-orange, day-flying males with feathery antennae contrast with flightless, grub-like grey females that never leave their cocoon to lay eggs.
