Acrobat Ant
A small ant named for its habit of raising its distinctive heart-shaped abdomen up over its body like an acrobat when disturbed or alarmed.
ant
Weaver Ant
A tree-dwelling ant that builds its nest by stitching living leaves together with silk produced by its own larvae, forming elaborate arboreal colonies defended fiercely by its workers.
ant
Pharaoh Ant
A tiny, pale-yellow ant that thrives almost exclusively indoors, forming vast interconnected colonies within the warm voids of heated buildings.
ant
Little Black Ant
A tiny, shiny jet-black ant that forms long, wandering foraging trails across lawns, patios, and kitchen counters in search of sweets and protein.
ant
Snipe Fly
A slender, long-legged fly often seen perched head-down on a sunny tree trunk or fence post, patiently watching for smaller insects to ambush. Its tapered, wasp-like abdomen and habit of resting motionless with legs splayed give it a distinctive, almost sentry-like posture in woodland clearings.
fly
Vinegar Fly
A tiny tan fly with bright red eyes that seems to appear out of nowhere the moment a banana starts to spoil, drawn in by the smell of fermentation rather than the fruit itself. Few insects have contributed more to the science of genetics, making this unassuming kitchen visitor one of the most studied animals on Earth.
fly
Pavement Ant
A stocky brown to black ant famous for the dramatic "ant wars" its colonies wage along sidewalk cracks each spring.
ant
Argentine Ant
A small, uniformly light-brown ant that forms enormous, cooperative supercolonies stretching across entire regions rather than defending small individual nests.
ant
Angle Shades Moth
A common night-flying moth whose forewings fold into a crumpled, tent-like shape that mimics a withered or damaged leaf, marked with bold olive-green and pinkish-brown zigzag bands.
moth
Carpenter Ant
A large, often shiny black ant that excavates smooth tunnels in dead or damp wood for nesting, recognizable by its size, evenly rounded thorax, and elbowed antennae.
ant
Anopheles Mosquito
A slim, mottled-winged mosquito best known for the distinctive head-down, tail-up posture it strikes while resting on walls and vegetation.
fly
Leafcutter Ant
A highly organized ant famous for marching in long trails while carrying disc-shaped pieces of leaf many times their own size, which they use to cultivate fungus gardens deep underground.
ant
Black Garden Ant
A familiar small, glossy black ant that forms visible foraging trails across patios and garden paths and nests beneath stones, pavers, and lawns.
ant
Odorous House Ant
A dark, unassuming ant best known for releasing a smell reminiscent of rotten coconut when a worker is crushed.
ant
Antheraea Silkmoth
A large, robust silkmoth in the genus Antheraea with broad reddish-brown to tan wings, each marked with a prominent transparent, eye-like spot, representing a group of giant moths long valued for producing wild silk.
moth
Squash Vine Borer
A day-flying, wasp-mimicking moth whose orange fuzzy hind legs and metallic wings make it easy to mistake for a wasp as it darts around squash vines.
moth
Louse 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.
fly
Scabies Mite
A microscopic, eyeless mite that spends its entire life cycle burrowed within the outer layer of a mammal's skin, among the smallest arachnids known to science. Unlike free-living mites, it has no independent existence away from a host and is studied primarily through microscopic examination rather than direct observation.
arachnid
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
Spider Mite
A speck-sized arachnid that spins fine silk webbing across infested leaves as it pierces plant cells for their contents, leaving behind a telltale stippled, bronzed appearance. Populations can explode rapidly in hot, dry weather, making it a familiar garden and greenhouse pest.
arachnid
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
Giant Centipede
A long, fast-moving, many-legged predator with a hardened segmented body and a pair of venom-injecting claws behind the head that it uses to overpower prey far larger than itself.
myriapod
Mormon Cricket
A hefty, flightless katydid whose swarms can stretch for miles across western rangelands, marching en masse in search of food and mates.
grasshopper-cricket
Golden Silk Orb-Weaver Spider
Famous for spinning enormous webs of shimmering golden silk, the golden silk orb-weaver is a large, long-legged spider of warm climates. Females dwarf the tiny males and hang head-down in their sprawling snares.
