Random Insect: Long-legged fly

Long-legged flies (Diptera: Dolichopodidae) are tiny insects, usually less than 0.2 inches (5 mm) in length. In spite of their diminutive size, most species are rather eye-catching because of their metallic green, blue, or bronze bodies and long legs. These flies live throughout the world, and over 1300 species can be found in North America alone. They’re especially common around swamps and marshes but can also be found in meadows and woodlands. Adults and the larvae of most species feed on other tiny insects, although some species have larvae that feed on plant material instead.

  1. Kind of reminds me of a horsefly. Does it bite?


  2. Ah…so that is what they are…

    It’s important to note that blow flies AKA bottle flies (Calliphoridae) are also metallic, but are a bit larger and have fatter bodies and shorter legs. They’re quite a bit more common near human habitations than long-legged flies. I’ve probably seen 1000 blow flies for every long-legged fly.

    They don’t bite people as far as I can tell.


  5. I thought they had the long legs, but I can watch.. There is a pond and wetland woods in the back. I appreciate what I learn here. Thank you… Michelle
