Firefly
A soft-bodied, dusk-flying beetle famous for the bioluminescent flashes it produces from its abdomen to attract mates on warm summer evenings.
beetle
Planthopper
A varied group of sap-feeding true bugs known for their sideways-held wings, jumping ability, and, in some tropical species, exaggerated head projections used for display.
true-bug
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
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
Chigger
A nearly microscopic mite larva that waits in clusters on grass tips for a passing host, taking a single brief meal before dropping away unseen. Only this larval stage is parasitic; the free-living adult spends its life hunting tiny prey in the soil.
arachnid
Africanized 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
Common Earwig
A flattened, reddish-brown insect instantly recognizable by the pair of pincer-like forceps at the tip of its abdomen, which it uses for defense and to help fold its wings.
other
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
Pond Skater
Skimming effortlessly across the surface of still water on long, spindly legs, the pond skater uses ripples to detect struggling insects, which it seizes and pierces with needle-like mouthparts.
true-bug
Red Velvet Mite
A plump, brilliant red mite covered in a dense coat of short velvety hairs, often seen emerging onto the soil surface in numbers right after a heavy rain. Its vivid color and unusual size for a mite make it one of the more eye-catching arachnids most people will ever encounter.
arachnid
Treehopper
A small, oddly shaped sap-feeding bug best known for an enlarged, often bizarre pronotum extending backward over its body, sometimes shaped like a thorn, leaf, or spike.
true-bug
Leaf Insect
A living illusion, this flattened green insect reproduces the veins, edges, and even blemishes of a real leaf so precisely that it can vanish while resting in plain sight.
mantis-stick
German Cockroach
A small, fast-moving light brown to tan roach marked with two dark parallel stripes running down its pronotum, most often seen scurrying for cover in warm, moist indoor areas.
other
Firefly Beetle
A soft-bodied, dark beetle famous for producing rhythmic flashes of light from its abdomen at dusk, using bioluminescence to attract mates on warm summer evenings.
beetle
Sowbug
A slate-gray, oval, armor-plated crustacean that shuffles through damp leaf litter on seven pairs of legs, recognizable by its overlapping segmented shell and pair of trailing tail-like appendages.
other
Marsh Treader
An extremely slender, thread-like true bug that walks slowly and deliberately across the water's surface on stilt-like legs, resembling a tiny floating twig as it hunts among marsh vegetation.
aquatic-insect
Earwig
A slender, reddish-brown insect easily identified by the pair of curved, forceps-like pincers at the tip of its abdomen, often found hiding under mulch, bark, or garden debris by day.
other
Common Water Strider
Skating effortlessly across the surface film of ponds and slow streams, the common water strider rows itself along on hair-fringed legs to ambush insects trapped in the surface tension.
true-bug
Green June Beetle
A large, velvety green scarab beetle with bronze edges that flies with a loud buzzing drone on warm summer days, often seen around ripening fruit.
beetle
Spittlebug
A small hopping true bug best known in its nymph stage, which surrounds itself in a frothy mass of white foam on plant stems, commonly called cuckoo spit.
true-bug
Mealybug
A soft, oval insect coated in a powdery white waxy secretion that gives it a fuzzy, cotton-like appearance, typically found clustered in leaf joints and along stems of houseplants.
true-bug
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
Fireflies
A soft-bodied beetle famous for producing rhythmic, glowing flashes of light from its abdomen at dusk, used to signal and attract mates across meadows and gardens on warm summer evenings.
