Soil Centipede
An extremely long, thin, worm-like centipede with dozens of leg pairs that burrows through soil using its elongated body rather than speed to get around.
myriapod
Centipede
A fast-moving, flattened, many-legged predator with one pair of long legs per body segment, instantly recognizable by its speed and, in the house centipede, its remarkably long, banded legs.
myriapod
Tiger Centipede
A large, banded desert centipede with alternating dark and pale segments reminiscent of tiger stripes, capable of a fast, muscular scuttle across sand and rock.
myriapod
Stone Centipede
A quick, flattened, reddish-brown centipede that darts for cover the instant its stone or log shelter is lifted, one of the most commonly seen centipedes in temperate gardens.
myriapod
Giant Centipede
A long, fast-moving, many-legged predator with a hardened segmented body and a pair of venom-injecting claws behind the head that it uses to overpower prey far larger than itself.
myriapod
House Centipede
A fast, wiry arthropod with 15 pairs of extremely long, banded legs that make it look far bigger than its actual body size, often seen darting across bathroom or basement floors at night.
myriapod
Amazonian Giant Centipede
The largest centipede on the planet, a formidable dark reddish-brown predator from South American rainforests capable of capturing prey as large as bats and small reptiles.
myriapod
Soil Mite
A microscopic, heavily armored mite found by the millions in a single handful of soil, quietly breaking down leaf litter and helping build the fertile ground beneath forests and fields.
arachnid
Fungus Gnat
A small, dark, mosquito-like fly with long legs and delicate smoky wings, often seen weakly fluttering around houseplants or crawling across damp potting soil.
fly
Digger Wasp
A solitary, ground-nesting wasp that excavates neat burrows in bare soil and provisions them with paralyzed prey for its young.
wasp
Root Maggot
A small, legless white grub that lives hidden in the soil, tunneling into the roots of cabbage-family vegetables where it feeds unseen.
fly
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
Cutworm
A plump, dull gray-brown caterpillar that hides in soil by day and emerges at night to sever young seedlings at the base, curling tightly into a C-shape when disturbed.
caterpillar-larva
Termite Swarmer
A dense, short-lived cloud of dark, equal-winged insects pouring from a crack in soil or wood, each one a would-be founder of a brand-new termite colony.
other
Mole Cricket
A stout, velvety brown cricket relative with broad, shovel-like front legs adapted for digging, spending most of its life burrowing just beneath the surface of moist soil.
grasshopper-cricket
Dampwood Termite
A relatively large termite that nests directly inside heavily moistened, decaying wood such as rotting logs and stumps, needing no soil contact but requiring consistently damp timber.
other
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
Cicada Killer Wasp
One of the largest wasps in North America, a robust rust-and-black or yellow-marked digger wasp that excavates burrows in bare soil and specializes in hunting cicadas to provision its underground nest.
wasp
Digger Bee
A robust, fast-flying, densely furry solitary bee that excavates tunnels in bare or sloped soil, often confused with bumble bees due to its bulky, hairy build and loud buzzing flight.
bee
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
Karner Blue
A tiny, silvery-blue butterfly dependent entirely on wild lupine and now known chiefly from a small number of protected sandy-soil habitats in the Great Lakes and Northeast.
butterfly
Earthworm
A long, smooth, segmented soil-dweller with no legs, eyes, or shell, best recognized by its ringed body and the pale saddle-like band (clitellum) found on mature individuals.
other
Jerusalem Cricket
A large, wingless, ground-dwelling insect with a shiny amber body, a strikingly human-like face, and a robust, banded abdomen, most often uncovered while digging in soil.
grasshopper-cricket
Drywood Termite
A termite that lives entirely within the dry wood it feeds on, needing no soil contact at all, and revealing itself mainly through small piles of pellet-like frass pushed from tiny exit holes.
