true-bug
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.

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
Isabella Tiger Moth (Woolly Bear)
Famous chiefly in its larval stage as the banded woolly bear caterpillar, this tiger moth's fuzzy black-and-rust-colored caterpillar is a familiar autumn sight, while the adult is a soft, tawny-orange moth with a stout, furry body.

A striking black swallowtail with iridescent blue-green hindwings and a row of round orange spots beneath, whose toxin-sequestering caterpillars make it a model for several butterfly mimics.
butterfly
Pipevine Swallowtail Caterpillar
A dark, velvety caterpillar studded with fleshy orange-tipped tubercles that feeds exclusively on pipevine, storing its host plant's chemistry for later defense as a butterfly.
caterpillar-larva
Rootworm
Working unseen below ground, rootworm larvae chew tunnels through the root systems of corn and other crops, the underground counterpart to the small, often striped or spotted beetles seen on leaves and flowers above.
beetle
Dung Beetle
A stout, often glossy black or metallic beetle famous for rolling, burying, or tunneling into animal dung, an unglamorous but ecologically vital habit that recycles nutrients back into the soil.
beetle
Green Peach Aphid
A small, pale yellow-green aphid with an exceptionally broad host range, recognized as one of the most widespread and adaptable aphid species found on garden vegetables, ornamentals, and stone fruit trees.
true-bug
