Weevil
A beetle instantly recognizable by its elongated, downward-curving snout tipped with tiny chewing mouthparts, used to bore into seeds, nuts, grain, and plant stems.
beetleThrips
A minuscule, slender insect with fringed, feather-like wings, often noticed only as a fast-moving dark speck darting across a flower petal or windowsill.

Mourning Cloak Butterfly
A deep maroon-brown butterfly bordered with a cream-yellow band and a row of iridescent blue spots, unusual among butterflies for overwintering as an adult and being one of the first to appear in early spring.
butterfly
Spined Soldier Bug
A predatory stink bug identified by the sharp, pointed spines projecting from its shoulders, valued in gardens and farm fields for hunting caterpillars, beetle larvae, and other pest insects.
true-bugHoverfly
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
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
Fall Armyworm
A brownish-green caterpillar marked with a pale inverted "Y" on its head, notorious for rapid, large-scale outbreaks that devastate corn and other grass crops across the globe.
caterpillar-larva
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.
beetleBraconid Wasp
A tiny, often overlooked parasitoid wasp best known for laying eggs inside caterpillars and other insect hosts, sometimes leaving telltale clusters of small white cocoons on a host's back.
waspSand 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.
wasp
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
Ladybug
A small, round, brightly colored beetle with a domed, shiny shell typically red or orange with black spots, one of the most recognizable and beloved beetles found in gardens worldwide.
beetle
Goliath Birdeater
The heaviest spider in the world, the Goliath birdeater is a massive, hairy tarantula from the South American rainforest whose leg span can rival a dinner plate, though despite its name it primarily hunts insects and other invertebrates rather than birds.
spider
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-bugGrub Worm
A plump, C-shaped, creamy-white larva with a distinct brown head, living underground where it feeds on grass and plant roots before eventually maturing into a scarab beetle.
beetleCodling Moth Larva
The classic 'worm in the apple,' this pinkish-white caterpillar tunnels straight to the core of apples and pears, leaving a telltale frass-plugged entry hole behind.
caterpillar-larvaWireworm
Slender, shiny, and armor-hard, the wireworm is the long-lived soil-dwelling larva of a click beetle, spending years underground feeding on seeds, roots, and tubers before ever taking beetle form.
beetleDobsonfly Larva (Hellgrammite)
A large, fierce-looking aquatic larva with strong pinching jaws and fringed side gills, spending years hunting under stream rocks before becoming a giant winged dobsonfly.
aquatic-insect
Whitefly
A tiny, moth-like white insect that clusters on the undersides of leaves and bursts into a snowy cloud when the plant is disturbed. Despite the name, it is not a true fly but a sap-feeding relative of aphids and scale insects.
true-bug
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.
beeWhite Grub
A pale, C-shaped larva with a brown head capsule and six stubby legs, spending its entire early life hidden underground feeding on roots before emerging as a stout May or June beetle.
beetleSoil Mite
A microscopic, heavily armored mite found by the millions in a single handful of soil, quietly breaking down leaf litter and helping build the fertile ground beneath forests and fields.
arachnid
Assassin Bug
A slender, long-legged predatory true bug with a curved, needle-like beak used to ambush and pierce other insects, often patterned in bold orange, black, or red warning colors.
true-bug
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.
