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.
arachnidFollicle Mite
An elongated, microscopic mite shaped almost like a tiny worm, living deep within hair follicles and oil glands of mammal skin where it spends its entire life largely unnoticed.
arachnid
Itch Mite
A microscopic, rounded mite that spends its entire life cycle within the skin of a mammalian host, invisible without a microscope.
arachnidSoil 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
Ear Mite
A microscopic, pale mite that lives out its entire life cycle within the ear canal of its host, completing egg to adult development in a warm, sheltered environment without ever leaving.
arachnidWater Mite
A brilliantly colored, ball-shaped mite that swims through freshwater ponds and streams using fringed, oar-like legs.
arachnidGall Mite
An almost worm-shaped, microscopic mite that induces plants to grow strange pouches, pockets, and felt-like patches around its feeding sites.
arachnidDust Mite
A microscopic, translucent arachnid that lives unseen in household dust, feeding quietly on shed skin flakes within mattresses, carpets, and furniture.
arachnidBird 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
Spider Mite
A speck-sized arachnid that spins fine silk webbing across infested leaves as it pierces plant cells for their contents, leaving behind a telltale stippled, bronzed appearance. Populations can explode rapidly in hot, dry weather, making it a familiar garden and greenhouse pest.
arachnidScabies 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
Clover Mite
A speck-sized reddish mite that streaks a rust-colored stain if crushed and invades homes by the hundreds when lawns dry out or turn cold.
arachnidChigger
A nearly microscopic mite larva that waits in clusters on grass tips for a passing host, taking a single brief meal before dropping away unseen. Only this larval stage is parasitic; the free-living adult spends its life hunting tiny prey in the soil.
arachnidHouse Dust Mite
A microscopic, translucent mite that lives unseen in household dust, feeding on shed skin flakes accumulated in bedding and furniture.
arachnidRed Velvet Mite
A plump, brilliant red mite covered in a dense coat of short velvety hairs, often seen emerging onto the soil surface in numbers right after a heavy rain. Its vivid color and unusual size for a mite make it one of the more eye-catching arachnids most people will ever encounter.
arachnid
Two-Spotted Spider Mite
A near-microscopic mite that spins fine silk webbing over leaves as it feeds, leaving foliage stippled and pale.
arachnid
Pseudoscorpion
A tiny, tail-less relative of true scorpions, complete with a pair of oversized pincers on a body barely bigger than a grain of rice. Often overlooked entirely, it spends its life hunting even smaller arthropods in leaf litter, bark, and sometimes old books.
arachnid
Minute Pirate Bug
A tiny, black-and-white patterned true bug barely visible without close inspection, the minute pirate bug is a voracious predator of thrips, mites, and insect eggs on flowers and foliage.
true-bug
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.
myriapodPsyllid
A tiny, sap-sucking hopper that resembles a miniature cicada and springs away in a blur when its host leaf is disturbed.
true-bug
Blacklegged Tick
A tiny, teardrop-shaped tick with dark legs and a reddish-brown abdomen that lurks in leaf litter along woodland trails.
arachnid
Money Spider
A tiny sheet-weaving spider, often seen drifting through the air on silk threads, traditionally said to bring good luck when it lands on you.
spiderMesh Web Weaver
A tiny, easily overlooked spider that spins a loose, bluish tangle of fuzzy silk over twig tips and seed heads to snare small insects.
spider
Cigarette Beetle
A tiny, reddish-brown, humpbacked beetle that rides along in stored dried herbs, spices, and tobacco wherever it hitches a ride.
