About the Green Jewel Fly

The Green Jewel Fly is a long-legged fly that looks like it was dipped in liquid metal, flashing emerald, gold, and blue as it pivots on top of a sunlit leaf. These tiny predators are a gardener's quiet ally, picking off aphids, gnats, and other small insects.

They are also among the most entertaining insects to watch at close range, skating across leaf surfaces in quick bursts and performing little wing-flicking courtship dances.

Photographing one is a test of patience and shutter speed; this metallic gem was caught at Bentsen-Rio Grande Valley State Park in Mission.
