Ebony Jewelwing

Fascinating facts about the Ebony Jewelwing

• You'll find them from Appalachia to the Great Plains, spanning the eastern United States and southeastern Canada right up to the western edge of the prairie. Their preferred homes are wooded streams and rivers, yet they aren't glued to the water's edge, they can wander far inland in search of food or mates.
• Their menu reads like a bug buffet, including tiger mosquitoes, giant willow aphids, fungus gnats, crane flies, large diving beetles, eastern dobsonflies, water fleas, green darners, caddisflies, rotifers, copepods, amphipods, dogwood borers, six-spotted tiger beetles, freshwater triclads, and even green hydra.
• Even birds and bats hunt these tiny pilots; great crested flycatchers, American robins, mallards, red-winged blackbirds, and blue jays swoop down, while reptiles like eastern painted turtles and snapping turtles snap them from the water's surface. Fish such as bluegill, largemouth bass, and channel catfish also gobble them, and mammals like the big brown bat join the chase at dusk. This extensive predator list highlights the jewelwing's role as a key energy link, transferring energy from aquatic insects up through multiple food webs.
• Male ebony jewelwings sporting a vivid blue-green body paired with stark black wings. In contrast, females wear dull brown bodies and smoky wings marked with tiny white spots near the tips, called pseudopterostigmas.
• Adults serve as both predator and prey: they hunt tiger mosquitoes, giant willow aphids, and even large diving beetles, while falling prey to birds such as the great crested flycatcher, reptiles like the eastern painted turtle, and fish including largemouth bass. Their position in this food web means they help control pest insects and, in turn, support higher trophic levels, highlighting their integral role in maintaining healthy freshwater ecosystems.
