Chicken Mite
A tiny, blood-feeding mite that hides in cracks and crevices of poultry housing by day and emerges at night to feed on roosting birds, turning a dull gray to deep red after a blood meal.
arachnidRootworm
Working unseen below ground, rootworm larvae chew tunnels through the root systems of corn and other crops, the underground counterpart to the small, often striped or spotted beetles seen on leaves and flowers above.
beetle
Bed Bug (Bat Bug)
A small, flat, reddish-brown, wingless true bug that hides in tight seams and crevices by day and feeds on blood at night, closely related to the bat bug, which occupies a similar niche in bat roosts.
true-bugCrane 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.
aquatic-insectSoldier 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-insectLouse Fly
A flattened, leathery-bodied fly that clamps onto fur or feathers with stout claws and scuttles sideways like a tiny crab rather than taking flight when disturbed. Several species shed their wings for good once they settle on a permanent host, spending the rest of their lives buried in fleece or plumage.
