Antheraea Silkmoth
A large, robust silkmoth in the genus Antheraea with broad reddish-brown to tan wings, each marked with a prominent transparent, eye-like spot, representing a group of giant moths long valued for producing wild silk.

arachnid
Golden Silk Orb Weaver
Suspended in a massive, glinting web strung between trees along a forest trail, the golden silk orb weaver is one of the largest and most striking web-building spiders in the Americas, spinning silk with a distinctive yellow-gold sheen.
spider
Goliath Birdeater
The heaviest spider in the world, the Goliath birdeater is a massive, hairy tarantula from the South American rainforest whose leg span can rival a dinner plate, though despite its name it primarily hunts insects and other invertebrates rather than birds.
spiderCave Cricket
Humpbacked and wingless with absurdly long legs and antennae, this pale, silent insect thrives in the total darkness of caves, basements, and damp crawl spaces.
grasshopper-cricketWhip Scorpion
A flattened, spider-like arachnid with a pair of extraordinarily long, whip-thin front legs used to feel out its surroundings in the dark, and large spiny pedipalps held out front like a crab's claws. Despite the name and fearsome appearance, it has no stinger and no fangs.
arachnid
Marbled Orbweaver
A round-bodied orb weaver with a swollen, marbled orange-and-purple abdomen that builds large, symmetrical webs in damp woodland edges.

spider
Spined Soldier Bug
A predatory stink bug identified by the sharp, pointed spines projecting from its shoulders, valued in gardens and farm fields for hunting caterpillars, beetle larvae, and other pest insects.

mantis-stickSoldier Fly
A wasp-mimicking fly with a flattened, often metallic body that spends its larval life quietly breaking down decaying plant matter or aquatic debris.
flyPlanthopper
A varied group of sap-feeding true bugs known for their sideways-held wings, jumping ability, and, in some tropical species, exaggerated head projections used for display.
true-bug
Squash Vine Borer
A day-flying, wasp-mimicking moth whose orange fuzzy hind legs and metallic wings make it easy to mistake for a wasp as it darts around squash vines.
mothCricket
A dark, round-headed jumping insect best known for the rhythmic chirping song produced by males rubbing their forewings together, often heard rather than seen after dusk.
grasshopper-cricket
Walking Stick
A remarkably twig-like insect with a long, slender, brown to green body and thin legs, so effective at mimicking a plant stem that it can be nearly invisible while motionless on vegetation.
mantis-stick
Hummingbird Hawk-Moth
A day-flying moth that hovers in front of flowers on blurring wings while unspooling a long proboscis to sip nectar, so closely mimicking a hummingbird in flight that it is frequently mistaken for one.
moth
Red-spotted Purple
A large, iridescent blue-black butterfly lacking tails, notable for closely mimicking the unpalatable Pipevine Swallowtail, with rows of red-orange spots visible along the underside wing margins.
butterflyKatydid
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.
