Vaporer Moth
A tussock moth with dramatic sexual differences: the male is a small rusty-brown day-flying moth with a white wing spot, while the female is a flightless, wingless gray sac-like insect that never leaves her cocoon.
mothSnipe 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.

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.
