Cross Orbweaver
Named for the pale cross of dots marking its rounded abdomen, the cross orbweaver spins one of the most classic wheel-shaped webs, rebuilding it fresh nearly every night to keep its silk sticky and effective.
spider
Tobacco Hornworm
A large, chunky green caterpillar with diagonal white stripes and a curved red-orange horn at its tail end, often found stripping tomato and tobacco plants.
caterpillar-larva
Small Tortoiseshell
A vivid orange-red European garden butterfly patterned with black and yellow blocks and a border of blue crescents, one of the most familiar and widely recognized butterflies across its range.
butterfly
Tobacco Hornworm Moth (Carolina Sphinx)
A large, streamlined gray-brown sphinx moth with six pairs of orange spots along its abdomen, best known as the adult stage of the tobacco hornworm caterpillar that feeds on tomato and tobacco plants.
moth
Tomato Hornworm Moth (Five-spotted Hawkmoth)
A large, robust grey-brown sphinx moth named for the five pairs of yellow-orange spots along its abdomen, best known as the adult form of the large green tomato hornworm caterpillar familiar to home gardeners.
moth
Purseweb Spider
A secretive, tube-dwelling spider that spends nearly its entire life hidden inside a silk-lined burrow extension camouflaged with soil and debris on the surface.
spider
Wood Tick
A flattened, ornately patterned tick that waits on low brush in the Rocky Mountain foothills, ready to grab onto large mammals passing within reach. Its mottled, shield-marked back makes it one of the more distinctive North American ticks to identify.
arachnid
Granary Weevil
A small, shiny, dark reddish-brown to black weevil with a long curved snout that is unable to fly, spending its entire life cycle within stores of wheat and other cereal grains.
beetle
Caddisfly Larva
A soft-bodied aquatic larva famous for building a portable protective case from sand, gravel, or plant debris bound together with silk.
aquatic-insect
Termite
A pale, soft-bodied social insect that lives in hidden colonies and feeds on cellulose in wood and plant debris, often mistaken for an ant despite belonging to an entirely different insect order.
other
Lone Star Tick
Named for the single silvery-white spot on the back of the adult female, the lone star tick is unusually active for a tick, moving toward hosts rather than simply waiting for them to pass. Its reddish-brown, ornamented body makes it one of the easier North American ticks to identify at a glance.
arachnid
Cave Spider
A long-legged orb weaver adapted to the twilight zone of caves, spinning large webs across cavern mouths and dangling its egg sacs from silk threads deep within the darkness.
spider
Caddisfly
A moth-like insect whose larvae are famous for constructing portable protective cases out of silk and whatever sand, twigs, or debris they can find.
aquatic-insect
Striped Bark Scorpion
A slender, tan scorpion marked with two bold dark stripes down its back, often found tucked under bark, rocks, or debris across the central United States.
arachnid
Camel Cricket
A wingless, humpbacked cricket with unusually long legs that gives it a spider-like appearance, often startling people when it turns up in damp basements or crawl spaces.
grasshopper-cricket
Africanized Honeybee (Killer Bee)
A hybrid strain of the western honey bee, nearly identical in appearance to common honey bees but known for more easily triggered, faster, and more numerous defensive responses when a colony is disturbed.
bee
Soldier 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.
fly
Whip 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
Soldier Fly Larva
Flattened, leathery, and tapered at both ends, the soldier fly larva drifts just beneath the surface film of ponds and marshes, filtering algae and organic debris while breathing through a fringe of water-repellent hairs at its tail.
aquatic-insect
Bird Mite
A minute, pale to reddish mite that lives among feathers and nesting material of wild and domestic birds, sometimes dispersing into nearby buildings when nests are abandoned.
arachnid
Rhinoceros Beetle
A massive, heavily armored beetle whose males sport a single large, curved horn projecting forward from the head, used to shove and flip rival males in contests of strength.
beetle
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
Stinging Rose Caterpillar
A boldly striped slug caterpillar in candy-like tones of yellow, orange, and purple, crowned with tufted spine clusters that can sting on contact.
