Katydid
A leaf-mimicking insect with broad, veined green wings shaped remarkably like foliage, best known for the loud, rhythmic 'katy-did, katy-didn't' chorus males produce on warm summer nights.

Common True Katydid
A living leaf that spends its life high in the treetops, the common true katydid is far more often heard than seen, producing the loud, rasping "katy-did, katy-didn't" chorus that fills eastern summer nights.
grasshopper-cricketMeadow Katydid
Small, slender, and beautifully camouflaged among grass blades, meadow katydids fill open fields and marsh edges with a soft, buzzy, insect-like ticking that blends into the summer evening background.
grasshopper-cricketCone-headed Katydid
A large, grass-colored katydid named for its sharply pointed, cone-shaped head, best known for producing some of the loudest, most sustained buzzing calls of any North American insect.
grasshopper-cricket
Angular-winged Katydid
A leaf-green katydid whose broad, leaf-shaped wings make it nearly invisible among tree foliage until its soft nighttime calls give it away.
grasshopper-cricket
Fork-tailed Bush Katydid
Slimmer and greener than its treetop relatives, the fork-tailed bush katydid lives among shrubs and garden plants, with males identified by the distinctive forked appendages at the tip of the abdomen that give the species its name.
grasshopper-cricket
Leaf-Footed Bug
A large, elongated brown true bug named for the flattened, leaf-shaped expansions on its hind legs, often found feeding on fruits, seeds, and vegetables in gardens and orchards.
true-bugLily Leaf Beetle
A brilliant scarlet-red beetle with a jet-black head, legs, and underside that feeds almost exclusively on true lilies and fritillaries, often stripping leaves down to bare stems.
beetleBush Cricket
Known by its long, thread-like antennae and evening chorus of chirps, this leaf-colored insect spends its life hidden among grass and foliage, often heard far more often than seen.
grasshopper-cricket
Roesel's Bush Cricket
Marked with a pale cream border along its thorax, this compact bush cricket produces a continuous, high-pitched, buzzing song reminiscent of an electrical hum from dense summer grass.
grasshopper-cricket
Speckled Bush Cricket
A tiny, plump, green insect finely dotted with dark speckles, this bush cricket forgoes song almost entirely, communicating instead through nearly silent, ultrasonic clicks.
grasshopper-cricket
Mormon Cricket
A hefty, flightless katydid whose swarms can stretch for miles across western rangelands, marching en masse in search of food and mates.
grasshopper-cricket
Great Green Bush Cricket
Europe's largest bush cricket, this brilliant grass-green insect fills warm summer evenings with a loud, sustained buzzing call audible from a considerable distance.
grasshopper-cricket
Great Golden Digger Wasp
A large, strikingly two-toned solitary wasp with a golden-haired thorax, reddish-orange midsection, and black-tipped abdomen, often seen digging burrows in bare soil to stock with paralyzed katydids and crickets.
wasp
Broad-Headed Bug
A slender, dark true bug with a notably wide head, whose nymphs are remarkable ant mimics that scurry among leaf litter before maturing into fliers that resemble small leaf-footed bugs.
true-bugLeaf Miner
Rather than chewing from the outside, a leaf miner larva tunnels between the upper and lower surfaces of a leaf, leaving behind pale, winding trails or blotches that trace its path as it feeds.
fly
Leafhopper
A small, wedge-shaped insect that darts sideways and springs away in quick hops when disturbed, often brightly striped or patterned and found clinging to the underside of leaves.
true-bug
Leafcutter Ant
A highly organized ant famous for marching in long trails while carrying disc-shaped pieces of leaf many times their own size, which they use to cultivate fungus gardens deep underground.
ant
Leafcutter Bee
A stout, dark-bodied bee best known not for how it looks but for the neat, circular or oval notches it cuts from leaves, which it uses to line and seal its nest cells.
bee
Milkweed Leaf Beetle
A large, boldly colored leaf beetle in glossy orange-red with irregular black patches, found feeding exclusively on milkweed plants alongside monarch caterpillars.
beetle
Western Conifer Seed Bug
A large brown true bug with flattened, leaf-shaped hind legs, native to conifer forests of the western United States but now widespread and notorious for gathering on and inside buildings as cooler weather approaches.
true-bug
Brimstone Butterfly
A sulphur-yellow, leaf-shaped butterfly whose folded wings mimic a fresh green leaf so convincingly it is often credited as the origin of the word 'butterfly'.
butterfly
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
Angle Shades Moth
A common night-flying moth whose forewings fold into a crumpled, tent-like shape that mimics a withered or damaged leaf, marked with bold olive-green and pinkish-brown zigzag bands.
