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.
arachnid
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
Water Mite
A brilliantly colored, ball-shaped mite that swims through freshwater ponds and streams using fringed, oar-like legs.
arachnid
Itch Mite
A microscopic, rounded mite that spends its entire life cycle within the skin of a mammalian host, invisible without a microscope.
arachnid
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.
arachnid
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
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.
arachnid
Dust Mite
A microscopic, translucent arachnid that lives unseen in household dust, feeding quietly on shed skin flakes within mattresses, carpets, and furniture.
arachnid
Gall Mite
An almost worm-shaped, microscopic mite that induces plants to grow strange pouches, pockets, and felt-like patches around its feeding sites.
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.
arachnid
Bird 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
Follicle 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
Two-Spotted Spider Mite
A near-microscopic mite that spins fine silk webbing over leaves as it feeds, leaving foliage stippled and pale.
arachnid
Red 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
House Dust Mite
A microscopic, translucent mite that lives unseen in household dust, feeding on shed skin flakes accumulated in bedding and furniture.
arachnid
Jumping Spider
A compact, often furry, day-active spider with unusually large forward-facing eyes that give it an alert, curious look, known for stalking prey and pouncing in a sudden leap.
spider
Grass Spider
Best known for the shimmering, dew-covered funnel webs that appear across lawns on autumn mornings, grass spiders are swift, striped runners that dash into a silken tunnel the instant prey - or a threat - approaches.
spider
Barn Spider
A brownish, mottled orb weaver famous as the inspiration for Charlotte's Web, commonly found spinning large nightly webs on barns, porches, and other structures.
spider
Banana Spider
"Banana spider" is a folk name applied inconsistently across the Americas, but in the southeastern United States it most often refers to the large, golden-silked orb weaver commonly seen spanning gaps between trees along shaded trails.
spider
Bold Jumping Spider
A stocky, fuzzy black spider with iridescent green or blue mouthparts and a bold white or orange spot on its abdomen, the bold jumper is known for its excellent eyesight, curious behavior, and ability to leap many times its own body length.
spider
Orb Weaver Spider
A stout-bodied spider best known for spinning the classic, near-perfect circular "orb" web strung between plants, eaves, or fences, often rebuilt fresh each night.
spider
Black Widow Spider
A glossy black, globe-bodied spider best known for the red or orange hourglass marking on the underside of the female's rounded abdomen, usually found tucked in a tangled web near ground level.
spider
Brazilian Wandering Spider
A fast, ground-dwelling hunter of the South American rainforest floor, the Brazilian wandering spider builds no web at all, instead actively roaming at night in search of prey and occasionally turning up in shipments of bananas, which earned it a widely known nickname.
spider
Chigger
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.
