Long-legged Fly (Chrysosoma spp.)


Detailing the physical features, habits, territorial reach and other identifying qualities of the Long-legged Fly.

The metallic Long-Legged Fly is fast and friendly, eating some annoying insects instead of human food.



This metallic green, copper or blue fly with bright red eyes can be found wandering between leaves in a forest, flowers in a meadow or along vegetation at the edges of ponds, lakes or marshes. Their legs are slightly longer in proportion to their bodies compared to other types of flies. They hold their wings away from their body instead of folding them flat against it.

They feed on smaller insects like aphids, mites, gnats, beetle larva and smaller flies. This makes them beneficial insects as they remove plant-harming predators.

Little is known about this fly's complete life cycle. Larvae have been found in rotten plant matter, but have also been found feeding on small aquatic organisms as well. This duplicity may be possible because the popular habitat for this fly is near water, allowing the larvae a more diverse growing and feeding ground.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
