Eastern Tailed-Blue
A tiny gossamer-wing butterfly with a delicate thread-like tail on each hindwing and a small orange spot near the tail base, common in open weedy habitats throughout the eastern half of North America.
butterflyBurying 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.
beetle
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
Sweat Bee
A small, often metallic green or bronze bee in the family Halictidae, named for its habit of landing on skin to sip perspiration, and an important generalist pollinator of wildflowers and crops.

beetle
Gray Hairstreak
A small slate-gray butterfly with thin white lines, an orange-capped black spot near the hindwing tail, and one of the broadest host-plant ranges of any North American butterfly, making it a familiar visitor to gardens and fields alike.
butterflySnipe 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.
flyBot 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.

Long-Legged Fly
A jewel-bright little fly that flashes metallic green, blue, or bronze in the sunlight as it darts across leaves on comically long, stilt-like legs, pausing to perform quick territorial displays. Both adults and larvae are active hunters of even smaller insects, making this tiny fly a useful predator in gardens and wetlands alike.
