Robber Fly
A powerfully built, bristly-faced predatory fly that ambushes other flying insects in midair, piercing them with a stout beak-like proboscis.
flyBumble Bee Queen
The large, robust foundress of a bumble bee colony, noticeably bigger and fuzzier than her worker offspring, seen alone in early spring searching for a nesting cavity before her colony's first workers emerge.
bee
Bee Fly
A fuzzy, bee-mimicking fly with a long, forward-pointing proboscis that hovers motionless in front of spring flowers while sipping nectar.
fly
Carpenter Bee
A large, robust bee closely resembling a bumblebee but with a shiny, mostly bald black abdomen, known for excavating tunnel nests into bare, untreated wood.
bee
Mining Bee
A furry, solitary ground-nesting bee that emerges in early spring in loose aggregations, often mistaken for a small bumble bee, digging individual burrows marked by small volcano-shaped mounds of soil.
beeDigger 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.
bee
Squash Bee
A robust, early-rising solitary bee specialized in visiting squash, pumpkin, and gourd flowers, often seen foraging in the cool early morning hours before many other pollinators are active.
bee
Mason Bee
A compact, metallic blue-black bee that nests in existing narrow cavities and seals its brood cells with mud, prized as one of the most efficient early-spring pollinators of fruit trees.
beeLonghorn Bee
A fuzzy, medium-sized solitary bee named for the males' notably long, curved antennae, commonly seen foraging on sunflowers, asters, and other late-summer composite flowers.
bee
Leafcutter Bee
A stout, dark-bodied bee best known not for how it looks but for the neat, circular or oval notches it cuts from leaves, which it uses to line and seal its nest cells.
bee
Cuckoo Bee
A slender, wasp-like bee that lacks pollen-carrying hairs because it never gathers its own pollen, instead sneaking into the nests of other solitary bees to lay eggs that hatch and consume the host's food stores.
bee
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
Honey Bee
A fuzzy, golden-brown and black-banded bee that lives in large, highly organized colonies, best known for its role in pollination and its production of wax comb and honey.
bee
Western Honey Bee
The familiar golden-brown, fuzzy-banded honey bee kept worldwide for honey production and crop pollination, living in large perennial colonies built around wax comb and a single egg-laying queen.
bee
Bumblebee Carpenter Bee
A large, robust bee that closely resembles a bumblebee at a glance but has a smooth, shiny, hairless abdomen and a habit of boring round nesting tunnels into bare wood.
bee
Blue Orchard Bee
A small, metallic blue-black solitary bee widely valued as an efficient early-spring pollinator of fruit trees, nesting in narrow tunnels and hollow stems rather than building hives.
bee
Wool Carder Bee
A stocky, yellow-and-black solitary bee named for its habit of scraping soft plant fibers from fuzzy leaves to line its nest, with territorial males that aggressively patrol and defend flower patches.

Fruit Fly (Vinegar Fly)
A tiny tan fly with bright red eyes that seems to appear from nowhere the moment a piece of fruit begins to overripen or a splash of wine is left uncovered.
flyWarble 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.
fly
Vinegar Fly
A tiny tan fly with bright red eyes that seems to appear out of nowhere the moment a banana starts to spoil, drawn in by the smell of fermentation rather than the fruit itself. Few insects have contributed more to the science of genetics, making this unassuming kitchen visitor one of the most studied animals on Earth.
fly
Stable Fly
A gray fly that looks almost identical to the common house fly, but carries a rigid, forward-pointing proboscis built for piercing skin rather than sponging up liquids.
fly
Sand Fly
A tiny, densely hairy fly that holds its wings erect in a distinctive V-shape and travels in short, silent hops rather than sustained flight.
flySnipe Fly
A slender, long-legged fly often seen perched head-down on a sunny tree trunk or fence post, patiently watching for smaller insects to ambush. Its tapered, wasp-like abdomen and habit of resting motionless with legs splayed give it a distinctive, almost sentry-like posture in woodland clearings.
flyPhorid Fly
A tiny, hump-backed fly best known for scuttling erratically across countertops and floors rather than taking flight, drawn to anything rotting or moist.
