Orchid Mantis
A dazzling pink-and-white mantis whose petal-shaped leg lobes let it pass as a flower, luring pollinating insects close enough to ambush.
mantis-stick
Common Housefly
A dull gray fly with four dark stripes on its thorax and large reddish eyes, one of the most widespread insects on Earth thanks to its close association with human food and waste.
fly
House Cricket
A pale tan, dark-banded cricket originally from warm regions of Asia that has spread worldwide both as an occasional indoor nuisance and as a widely farmed feeder insect.

moth
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
Tachinid Fly
A bristly, house-fly-like insect that looks unremarkable at a glance but hides one of the most important ecological roles among flies: its larvae develop as internal parasites of caterpillars, beetles, and other insects, quietly regulating populations across the landscape. Gardeners often welcome tachinid flies as natural allies against crop-damaging pests.
