Summary

[edit]
Description

Leucopis sp. Rock Creek Park, Washington, DC, USA.

This little fly hung around a bunch of aphids tended by ants. It looked like it was licking honey dew from the aphids. The larvae are predators of plant-parasitic Hemiptera.

I think Leucopis argenticollis and L. piniperda. are the only Leucopis species in the eastern U.S. They were introduced here to control hemlock woolly adelgid: <a href="http://www.srs.fs.usda.gov/compass/2015/05/27/bad-news-for-the-hemlock-woolly-adelgid/" rel="nofollow">www.srs.fs.usda.gov/compass/2015/05/27/bad-news-for-the-h...</a>
