fly
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.
fly
Bordered Plant Bug
A dark, oval-bodied true bug with a distinct pale margin around its wing edges, often mistaken for a large ant or beetle when its nymphs cluster together in tight groups.
true-bug
Trapdoor Spider
A stocky, burrowing spider that engineers a hinged, camouflaged silk door over its underground tunnel, waiting just inside to snap the lid open and seize passing prey in an ambush lasting a fraction of a second.
spider
Band-winged Grasshopper
A camouflaged grasshopper that flashes vivid yellow, red, or blue hindwings in flight before vanishing again into the dust the instant it lands.

A large, robust grey-brown sphinx moth named for the five pairs of yellow-orange spots along its abdomen, best known as the adult form of the large green tomato hornworm caterpillar familiar to home gardeners.
moth
Meadow Katydid
Small, slender, and beautifully camouflaged among grass blades, meadow katydids fill open fields and marsh edges with a soft, buzzy, insect-like ticking that blends into the summer evening background.
grasshopper-cricket
Chigger
A nearly microscopic mite larva that waits in clusters on grass tips for a passing host, taking a single brief meal before dropping away unseen. Only this larval stage is parasitic; the free-living adult spends its life hunting tiny prey in the soil.
