Crane Fly
A long-legged, mosquito-like fly with a slender tan or gray body and a single pair of narrow wings, often seen wobbling clumsily around outdoor lights on summer evenings.
flyLouse Fly
A flattened, leathery-bodied fly that clamps onto fur or feathers with stout claws and scuttles sideways like a tiny crab rather than taking flight when disturbed. Several species shed their wings for good once they settle on a permanent host, spending the rest of their lives buried in fleece or plumage.
flyTsetse Fly
A stout grayish-brown fly of African woodlands whose rigid, forward-jutting proboscis and scissor-folded wings set it apart from any ordinary house fly.
flyMarsh Fly
A slender, unassuming fly best known for larvae with a remarkable diet: nearly every species in the family feeds on aquatic or terrestrial snails and slugs, making marsh flies natural specialists in wetland food webs. Adults are often found resting quietly on sedges and other marsh vegetation near the water's edge.

Cicada
A stout, big-eyed insect best known for the loud, buzzing chorus of song produced by males, and for periodical species that emerge from the ground by the millions after living underground for over a decade.
true-bugSoldier Fly
A wasp-mimicking fly with a flattened, often metallic body that spends its larval life quietly breaking down decaying plant matter or aquatic debris.
flyIchneumon Wasp
A slender, long-antennaed parasitoid wasp, often mistaken for a giant mosquito or a stinging insect, that is best known for the extraordinarily long ovipositor some species use to drill into wood and lay eggs on hidden larvae.
waspPhorid Fly
A tiny, hump-backed fly best known for scuttling erratically across countertops and floors rather than taking flight, drawn to anything rotting or moist.
flyWarble 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.
flyTermite Swarmer
A dense, short-lived cloud of dark, equal-winged insects pouring from a crack in soil or wood, each one a would-be founder of a brand-new termite colony.
otherRat-Tailed Maggot
Named for its long, thin, telescoping breathing tube, the rat-tailed maggot is the aquatic larva of the drone fly, thriving in stagnant, low-oxygen water where few other insects can survive.
aquatic-insect
Blue Bottle Fly
A robust fly with a glossy, metallic blue-black body and a loud buzzing flight, commonly seen around outdoor waste and occasionally indoors, easily recognized by its shiny coloring and bristly frame.
flyFungus Gnat
A small, dark, mosquito-like fly with long legs and delicate smoky wings, often seen weakly fluttering around houseplants or crawling across damp potting soil.
flyPunkie
An almost invisibly small biting fly that swarms near wetlands at dusk, where only the females take blood meals from animal hosts.
flySoldier Fly Larva
Flattened, leathery, and tapered at both ends, the soldier fly larva drifts just beneath the surface film of ponds and marshes, filtering algae and organic debris while breathing through a fringe of water-repellent hairs at its tail.
aquatic-insectRoot Maggot
A small, legless white grub that lives hidden in the soil, tunneling into the roots of cabbage-family vegetables where it feeds unseen.
fly
Fruit Fly (Vinegar Fly)
A tiny tan fly with bright red eyes that seems to appear from nowhere the moment a piece of fruit begins to overripen or a splash of wine is left uncovered.
fly
Walking Stick Insect
A master of disguise that has evolved to look almost exactly like a twig, bark or leaf, remaining motionless for hours to avoid the notice of hungry birds and lizards.
mantis-stick
Black Soldier Fly
A sleek, dark, wasp-like fly whose larvae are voracious decomposers of decaying organic material, while the short-lived adults do not feed at all.
flyAlderfly
A small, dusky-winged insect that flutters weakly among streamside alders and shrubs, the diminutive relative of the mighty dobsonfly.
aquatic-insect
Lacewing
A delicate, pale green insect with large, transparent, intricately veined wings and shining golden or copper-colored eyes, valued as a natural predator of aphids in its larval form.

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.
