I found this larva in a tree that was rotting in a forest in Northern Illinois. I was searching for fungus gnats but did not find any. I took a cup of the rotting material and processed it in a Belize Funnel and got this critter. It has grown considerably in the week since I found it eating? There were some Drosophila melanogaster larvae available as well as potting soil in the container where it was kept. The posterior reminds me of a dolichopod, but the anterior end does not look a thing like a doli.
