Carolina Mantis
A mottled gray-brown mantis native to the southeastern and south-central United States, smaller and more camouflaged than its introduced Chinese relative, and recognized as the state insect of South Carolina.
mantis-stick
Ground Beetle
A fast-moving, shiny black or metallic beetle with long legs and prominent jaws, usually found scurrying under rocks and debris where it hunts other small invertebrates.
beetle
European Paper Wasp
A slender, orange-antennaed social wasp that builds small, open umbrella-shaped paper combs under eaves and ledges, now common well beyond its native European range.
waspBrown Lacewing
Smaller and less conspicuous than its green relatives, the Brown Lacewing is a subtle but effective predator of aphids and other tiny insects in gardens, forests, and orchards.
other
American Lady
A boldly patterned orange-and-black brushfoot butterfly best identified by two large eyespots on its underside hindwing and a distinctive small white spot within the orange field of its forewing.
butterfly
Silvery Checkerspot
An orange-brown checkered butterfly named for the row of small silvery-white crescent spots along the underside hindwing margin, commonly seen nectaring at composite flowers in open habitats.
butterflyBraconid 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.
waspBlister 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
Longhorn Beetle
A beetle instantly recognizable by antennae often longer than its own body, ranging from small woodland species to large, dramatically patterned tropical and temperate forms.
beetleBurying Beetle
A black beetle marked with bold orange-red bands, notable for locating small dead animals, burying them underground, and cooperatively raising larvae with a partner over the buried carcass.
beetleGiant Weta
One of the world's heaviest insects, a giant flightless cricket relative endemic to New Zealand that has survived for millions of years by filling the ecological role usually taken by small mammals.
grasshopper-cricket
Bluet Damselfly
Small and delicate, bluet damselflies flash brilliant blue and black along the vegetated edges of ponds and lakes, forming mating pairs that fly in tandem while laying eggs directly into plant stems underwater.
dragonflyRootworm
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.
beetleAlderfly Larva
Fringed with feathery gill filaments along its sides, the alderfly larva crawls through soft pond and stream sediments hunting smaller invertebrates before eventually leaving the water entirely to pupate on land.
aquatic-insect
Southern Green Stink Bug
A large, shield-shaped, solid bright green true bug found on a wide variety of garden and crop plants across warm regions worldwide, recognizable by its broad body and, in some individuals, a row of small pale dots along the shoulders.
true-bug
Pseudoscorpion
A tiny, tail-less relative of true scorpions, complete with a pair of oversized pincers on a body barely bigger than a grain of rice. Often overlooked entirely, it spends its life hunting even smaller arthropods in leaf litter, bark, and sometimes old books.
arachnid
Eastern Comma
A ragged-edged orange-and-brown woodland butterfly named for the small, silvery comma-shaped mark on the underside of its hindwing, with a cryptic dead-leaf pattern that camouflages it perfectly when its wings are closed.
butterfly
Eastern Forktail
One of the smallest and most adaptable damselflies in eastern North America, the Eastern Forktail thrives in everything from wild marshes to roadside ditches, with bright green-and-black males and color-changing females.
otherHorse Fly Larva
Hidden in the wet mud along pond and stream margins, the horse fly larva is a tapered, tough-skinned predator that hunts other small soil and mud-dwelling invertebrates before eventually transforming into the familiar biting fly.
aquatic-insectBot Fly
A stocky, bumblebee-mimicking fly whose adults never feed and live only long enough to mate and locate a rodent or rabbit burrow for their eggs. Despite their harmless, buzzing adult stage, bot flies are best known through the larvae that develop as internal parasites of small mammals.
fly
Screwworm Fly
A metallic blue-green blowfly whose larvae are unusual among maggots for feeding on living tissue rather than carrion, drawn to even small open wounds on warm-blooded animals. The species has been the target of one of the most successful large-scale insect eradication campaigns in history across much of North America.
flyScabies 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
Aphid
A tiny, soft-bodied, pear-shaped insect that clusters in dense colonies on plant stems and leaf undersides, feeding on sap through needle-like mouthparts and often coated in sweet honeydew.
true-bugArmy Ant
A nomadic predator that never builds a permanent nest, instead forming temporary living bivouacs from its own linked bodies and sweeping through the forest floor in massive predatory raids.
