Flower Chafer Beetle
Often clad in brilliant metallic greens, golds, and bronzes, flower chafers are day-flying scarab beetles that feed on flowers. Many buzz loudly in flight and keep their wing covers closed as they take off.
beetleLonghorn 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.

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.
beetleAsian 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
Cucumber Beetle
A small, brightly colored beetle patterned with black spots or stripes on a yellow-green background, commonly seen crawling on the flowers and leaves of cucumber and squash plants.
beetle
Soldier Beetle
A slender, soft-bodied beetle in orange and black or yellow and brown, often seen clustered on late-summer flowers where it feeds on pollen, nectar, and small insects.
beetleBlister Beetle
An elongated, soft-bodied beetle with a distinctly narrow neck, often seen feeding in small groups on flowers, and known for releasing a defensive chemical from its leg joints when disturbed.
beetle
Palo Verde Beetle
One of the largest beetles in North America, a heavy, dark reddish-brown longhorn beetle with long spiny antennae and a loud, buzzing flight that emerges from the desert soil around palo verde and mesquite trees in summer.
beetlePine Sawyer Beetle
A large, long-antennaed longhorn beetle of pine and spruce forests, mottled gray-brown to black, that produces a rasping sound when handled and whose larvae tunnel deep into dead or dying conifer wood.
beetle
Locust Borer
A slender black longhorn beetle boldly striped with yellow, closely resembling a wasp, commonly seen visiting goldenrod flowers in autumn near black locust trees.
beetle
Flour Beetle
A tiny, shiny reddish-brown beetle that infests flour, cereal, and other dry stored foods, often found in dense clustered populations.
beetle
Old House Borer
A grayish-brown to nearly black longhorn beetle whose larvae bore extensively through structural softwood, capable of causing large galleries hidden beneath the wood surface.
beetle
Confused Flour Beetle
A tiny, flattened, reddish-brown beetle commonly found in stored flour and grain products, distinguished from its near-identical relative the red flour beetle mainly by its antennae shape.
beetle
Red Flour Beetle
A tiny, flattened, rust-red beetle found in stored flour and grain worldwide, capable of flight and closely resembling the confused flour beetle apart from the shape of its antennal club.
beetle
Rose Chafer
A slender, tan, long-legged scarab beetle that gathers in swarms on rose blossoms and other flowers in late spring, chewing petals and foliage into a lacy, skeletonized pattern.
beetle
Cottonwood Borer
A large, boldly patterned longhorn beetle in black and chalky white checkerboard markings, often found clinging to the trunks of cottonwood and poplar trees near its larvae's root tunnels.
beetle
Boll Weevil
A small, grayish-brown snout beetle with a long, curved rostrum, historically famous for its close feeding association with cotton flower buds and bolls.
beetleRootworm
Working unseen below ground, rootworm larvae chew tunnels through the root systems of corn and other crops, the underground counterpart to the small, often striped or spotted beetles seen on leaves and flowers above.
beetle
Mealworm
A tan, segmented larva with a shiny hard exoskeleton that tunnels through stored grain and flour before transforming into a darkling beetle.
