Search and identify bugs & insects — beetles, butterflies, moths, ants, bees, spiders and more — with size, habitat, danger, behavior, and how to tell them apart.
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
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
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
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
Digger Bee
A robust, fast-flying, densely furry solitary bee that excavates tunnels in bare or sloped soil, often confused with bumble bees due to its bulky, hairy build and loud buzzing flight.

Sweat Bee
A small, often metallic green or bronze bee in the family Halictidae, named for its habit of landing on skin to sip perspiration, and an important generalist pollinator of wildflowers and crops.
bee
Ruby Meadowhawk
A small, brilliant-red dragonfly of late summer meadows, so intensely colored that mature males seem to glow when perched low in the grass.
dragonfly
Dog Tick
A flattened, oval arachnid with mottled silvery markings that waits on grass tips and low brush for a passing host to climb aboard and attach.
arachnid
Wandering Spider
A large, fast-moving hunter that forages actively at night across leaf litter and low vegetation instead of relying on a web to catch its meals.
spider
Common Wood-Nymph
A large brown grassland butterfly with a bold yellow patch and one or two prominent black eyespots on the forewing, known for its bouncing, low-to-the-ground flight.
butterfly
Bumblebee
A large, round, densely furry bee with bold black-and-yellow banding, known for its loud, low-pitched buzz and its ability to fly and forage in cooler temperatures than most other bees.
bee
Wood Tick
A flattened, ornately patterned tick that waits on low brush in the Rocky Mountain foothills, ready to grab onto large mammals passing within reach. Its mottled, shield-marked back makes it one of the more distinctive North American ticks to identify.
arachnid
Warble Fly
A furry, bee-mimicking fly that never lands on flowers or feeds as an adult, spending its brief life darting around grazing cattle to lay eggs on their legs and lower body. Herds sometimes react with sudden panicked runs, known as gadding, whenever a warble fly approaches.
