Tailless Whip Scorpion
A flattened, spider-like arachnid with no stinger and no fangs, instead using a pair of long whip-like sensory legs and grasping spiny arms to feel out and seize prey in total darkness.
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
Digger Wasp
A solitary, ground-nesting wasp that excavates neat burrows in bare soil and provisions them with paralyzed prey for its young.

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.

Cave 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-cricket
Marbled Orbweaver
A round-bodied orb weaver with a swollen, marbled orange-and-purple abdomen that builds large, symmetrical webs in damp woodland edges.

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
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
Spiny Orb Weaver
A small, hard-shelled orb weaver shaped like a tiny crab, with six sharp spines projecting from a brightly colored abdomen suspended in a neat wheel-shaped web.
spider

dragonfly
Mining Bee
A furry, solitary ground-nesting bee that emerges in early spring in loose aggregations, often mistaken for a small bumble bee, digging individual burrows marked by small volcano-shaped mounds of soil.
bee

moth
Pink Toe Tarantula
An agile, tree-dwelling tarantula with a dark velvety body and distinctive pale pink tips on its feet, the pink toe spends nearly its entire life above ground, spinning silk retreats among leaves and bark high in the rainforest canopy.
spider

A large, industrious desert ant that clears a bare, sunburned disk of ground around its nest entrance while collecting and storing seeds by the thousands.
ant
Slug
A soft-bodied, shell-less land mollusk that glides on a muscular foot, leaving a silvery mucus trail as it forages across damp ground and vegetation.

Heavy-bodied and slow-moving, lubber grasshoppers make up for their poor flying ability with large size, bold coloring, and a lumbering, ground-bound lifestyle.
grasshopper-cricket
Common Wood-Nymph
A large brown grassland butterfly with a bold yellow patch and one or two prominent black eyespots on the forewing, known for its bouncing, low-to-the-ground flight.
butterfly

A tiny, pale lemon-yellow butterfly with a thin, crisp black wing border, fluttering close to the ground in fields and roadsides across the southern and eastern United States.
butterfly
Bark Scorpion
A slender, pale tan scorpion best known for its unusual habit of climbing trees, walls, and rock faces rather than staying on the ground like most scorpions. Its thin build and long, narrow tail set it apart from the stockier, heavy-clawed scorpions found elsewhere.
arachnid
Fireflies Larvae Glowworm
The larval form of fireflies, often called glowworms, are flattened, segmented crawlers that glow with a steady greenish light. These little predators hunt slugs, snails, and worms in damp ground.
