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
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
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
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
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
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
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
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
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
Two-Spotted Spider Mite
A near-microscopic mite that spins fine silk webbing over leaves as it feeds, leaving foliage stippled and pale.
arachnid
Bird-dropping Spider
A lumpy, white-and-brown orb-weaver that spends its days motionless on a leaf, looking uncannily like a fresh splash of bird droppings.
spider
Birdwing Butterfly
Among the largest butterflies on Earth, birdwings soar through rainforest canopies on angular, bird-like wings. Males dazzle with iridescent greens, golds, and blues, while the larger females wear more subdued browns.
butterfly
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.
arachnid
American Grasshopper
A large, strong-flying grasshopper related to the locusts of the Old World, the American grasshopper can occasionally form dense, damaging aggregations across the southern United States.

Goliath Birdeater
The heaviest spider in the world, the Goliath birdeater is a massive, hairy tarantula from the South American rainforest whose leg span can rival a dinner plate, though despite its name it primarily hunts insects and other invertebrates rather than birds.
spider
Tarantula
The tarantula is the heavyweight of the spider world, a densely furred, ground-hugging hunter that spends most of its long life waiting in a silk-lined burrow for prey to wander past.
spider
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
Walking Stick Insect
A master of disguise that has evolved to look almost exactly like a twig, bark or leaf, remaining motionless for hours to avoid the notice of hungry birds and lizards.
mantis-stick
Mormon Cricket
A hefty, flightless katydid whose swarms can stretch for miles across western rangelands, marching en masse in search of food and mates.
