Red Wood Ant
A large woodland ant with a reddish-brown thorax and dark abdomen, famous for building towering dome-shaped mounds of pine needles and twigs in forest clearings.
ant
Odorous House Ant
A dark, unassuming ant best known for releasing a smell reminiscent of rotten coconut when a worker is crushed.
ant
Antlion
An insect best known for its larval stage, the doodlebug, which digs a small conical pit trap in loose sand to ambush unwary ants, while the winged adult resembles a slender, delicate damselfly.
other
Termite
A pale, soft-bodied social insect that lives in hidden colonies and feeds on cellulose in wood and plant debris, often mistaken for an ant despite belonging to an entirely different insect order.
other
Broad-Headed Bug
A slender, dark true bug with a notably wide head, whose nymphs are remarkable ant mimics that scurry among leaf litter before maturing into fliers that resemble small leaf-footed bugs.
true-bug
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.

Mud Dauber Wasp
Slender, long-waisted wasps that build distinctive nests from mud, mud daubers stock their cells with paralyzed spiders. Their tube or urn-shaped mud nests are common under eaves and bridges.
wasp
Soft Tick
A wrinkled, leathery, bean-shaped tick that hides by day in nests and cracks, emerging briefly at night to feed and then vanish again.
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
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
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
Paper Wasp
A slender, long-legged wasp with a narrow waist and reddish-brown to black coloring marked with yellow, recognized by its open, umbrella-shaped paper nest with visible hexagonal cells.
wasp
Formosan Subterranean Termite
A pale, aggressive subterranean termite native to East Asia that builds enormous colonies and can construct large above-ground carton nests in trees, walls, and structures.
other
Dampwood Termite
A relatively large termite that nests directly inside heavily moistened, decaying wood such as rotting logs and stumps, needing no soil contact but requiring consistently damp timber.
other
Red Paper Wasp
A large, rusty-red paper wasp that builds open, umbrella-shaped nests under eaves and in sheltered structures, often seen hovering near its comb.
wasp
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
Wasp
A slender-waisted, smooth-bodied flying insect typically banded in black and yellow, recognizable by its narrow 'wasp waist' and folded wings, and often social, building paper nests in colonies.
wasp
Hornet
A large, robust social wasp with a reddish-brown and yellow patterned body, notably bigger than yellowjackets, building enclosed papery nests often high in tree cavities or wall voids.
wasp
Cicada Killer Wasp
One of the largest wasps in North America, a robust rust-and-black or yellow-marked digger wasp that excavates burrows in bare soil and specializes in hunting cicadas to provision its underground nest.
wasp
Mud Dauber
A slender, non-aggressive solitary wasp with a distinctively long, thread-like waist, known for constructing tube- or pot-shaped nests out of mud pellets on walls and eaves.
wasp
Bordered Plant Bug
A dark, oval-bodied true bug with a distinct pale margin around its wing edges, often mistaken for a large ant or beetle when its nymphs cluster together in tight groups.
true-bug
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
Bald-faced Hornet
A black-and-white social wasp, actually a type of yellowjacket rather than a true hornet, best known for building large, football-shaped gray paper nests suspended from tree branches or eaves.
wasp
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.
