Crane Fly Larva
Thick-skinned and worm-like, the crane fly larva, often called a leatherjacket, burrows through wet mud and decaying vegetation at the edges of ponds and streams, breaking down plant material as it grows.

Trapdoor Spider
A stocky, burrowing spider that engineers a hinged, camouflaged silk door over its underground tunnel, waiting just inside to snap the lid open and seize passing prey in an ambush lasting a fraction of a second.

Great Golden Digger Wasp
A large, strikingly two-toned solitary wasp with a golden-haired thorax, reddish-orange midsection, and black-tipped abdomen, often seen digging burrows in bare soil to stock with paralyzed katydids and crickets.

Emperor Scorpion
A massive, glossy black scorpion with heavy, oversized pincers built for crushing prey rather than stinging it, the emperor scorpion is one of the biggest and most recognizable scorpions on Earth. It digs deep burrows in rainforest soil and is unusual among scorpions for tolerating close family groups.
arachnid
Bot Fly
A stocky, bumblebee-mimicking fly whose adults never feed and live only long enough to mate and locate a rodent or rabbit burrow for their eggs. Despite their harmless, buzzing adult stage, bot flies are best known through the larvae that develop as internal parasites of small mammals.
fly
Scabies Mite
A microscopic, eyeless mite that spends its entire life cycle burrowed within the outer layer of a mammal's skin, among the smallest arachnids known to science. Unlike free-living mites, it has no independent existence away from a host and is studied primarily through microscopic examination rather than direct observation.
arachnid
Backswimmer
A boat-shaped aquatic true bug that swims upside down using oar-like hind legs, patrolling pond water in search of small prey.
aquatic-insect
Pill Millipede
A short, heavily armored millipede that rolls into a tight, perfect ball when disturbed, closely resembling a pill bug but built from far fewer, broader body segments.
myriapod
Lesser Water Boatman
A flat-backed, oar-legged true bug that rows through pond water with fringed hind legs, surfacing periodically to trap a silvery bubble of air against its body.
true-bug
Meadow Spittlebug
A small, mottled hopping true bug whose immature nymphs are far more often noticed than the adults, hidden inside frothy blobs of white foam known as cuckoo spit on plant stems.
true-bug
Boll Weevil
A small, grayish-brown snout beetle with a long, curved rostrum, historically famous for its close feeding association with cotton flower buds and bolls.
