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
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
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
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
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.
beeWarble 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.
flyHorse Fly
A stout, fast-flying fly with large iridescent eyes and a heavy, robust body, known for its persistent, buzzing pursuit of large mammals on warm summer days.
fly
House Fly
A gray, fuzzy-bodied fly with four dark stripes on its thorax and large reddish compound eyes, famous for its erratic buzzing flight and tendency to land repeatedly on food and surfaces.
fly
Screwworm Fly
A metallic blue-green blowfly whose larvae are unusual among maggots for feeding on living tissue rather than carrion, drawn to even small open wounds on warm-blooded animals. The species has been the target of one of the most successful large-scale insect eradication campaigns in history across much of North America.
flyHoverfly
A slender, bee- or wasp-patterned fly known for its remarkable ability to hover motionless in midair before darting suddenly to a new flower.
fly
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
Honeybee
A fuzzy, golden-brown and black social bee that lives in large colonies, builds wax honeycomb, and is the primary managed pollinator of crops and wildflowers worldwide.
bee
Common Housefly
A dull gray fly with four dark stripes on its thorax and large reddish eyes, one of the most widespread insects on Earth thanks to its close association with human food and waste.
fly
Tachinid Fly
A bristly, house-fly-like insect that looks unremarkable at a glance but hides one of the most important ecological roles among flies: its larvae develop as internal parasites of caterpillars, beetles, and other insects, quietly regulating populations across the landscape. Gardeners often welcome tachinid flies as natural allies against crop-damaging pests.
fly
Death's-head Hawkmoth
A large, thick-bodied hawkmoth instantly recognized by the pale, skull-and-crossbones marking on its furry thorax, famous for entering beehives and letting out a shrill squeak when disturbed.
mothSand Wasp
A fast, sun-loving solitary wasp with large green or grayish eyes and yellow-striped markings that digs burrows in loose sand and provisions them almost entirely with flies.
waspDigger 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
Bess Beetle
A large, glossy jet-black beetle that lives in family groups inside rotting logs, communicating with fellow beetles through squeaks and cooperating to raise larvae, an unusually social lifestyle for an insect of its kind.
beetle
Stag Beetle
A large, glossy beetle whose males wield oversized, antler-like mandibles resembling a stag's rack of horns, used for wrestling rival males rather than for feeding.
beetle
Fig Beetle
A large, dull metallic-green scarab beetle with a loud, buzzing flight, often seen crash-landing near ripe or overripe fruit and compost piles on warm summer days.
beetle
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.
