moth
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.
beeAsian Longhorned Beetle
A large, glossy black longhorn beetle patterned with irregular white spots and boldly banded blue-white antennae, notable as one of the largest and most eye-catching wood-boring beetles seen in temperate hardwood trees.
beetle
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
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.
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
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
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
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
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.
beeBumble 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.
beeAfricanized Honeybee (Killer Bee)
A hybrid strain of the western honey bee, nearly identical in appearance to common honey bees but known for more easily triggered, faster, and more numerous defensive responses when a colony is disturbed.
bee
Longhorn Beetle
A beetle instantly recognizable by antennae often longer than its own body, ranging from small woodland species to large, dramatically patterned tropical and temperate forms.
beetleKatydid
A leaf-mimicking insect with broad, veined green wings shaped remarkably like foliage, best known for the loud, rhythmic 'katy-did, katy-didn't' chorus males produce on warm summer nights.
grasshopper-cricket
Atlas Beetle
A large, glossy black-to-metallic rhinoceros beetle in which males bear three long curved horns used for combat over food and mates.
beetle
Titan Beetle
One of the largest insects on Earth, the titan beetle is a colossal longhorn from the Amazon whose body can exceed 16 cm. Its powerful jaws and loud hiss make it an imposing rainforest giant.
