Summary[edit] Description: English: Root Maggot Fly - Eutrichota lipsia, Woodbridge, Virginia. The larvae of this fly are only found in Groundhog burrows. We have a groundhog burrow in our back yard, so it's not surprising that this fly was found there. Date: 27 October 2013, 15:20:45. Source: https://www.flickr.com/photos/52450054@N04/10740402986/.
