Fungus gnat larvae

Fungus gnat larvae

5961   I found these clumps of larvae in my backyard in Sylvan Lake, Alberta as the snow was melting now in April 2017. There are at least 2 dozen clumps of larvae often with a larger reddish worm nearby. We have a dog but the larvae weren’t even near any of the stool piles that we missed picking up throughout the winter. So I’m really hoping they aren’t pin worms and maybe just earthworm larvae that had to surface due to the excessive moisture in the ground. The yard doesn’t see much sun and with all the snow it becomes like a glacier in spring. Can’t find any photos like it and we have lived here for 15 years and have never experienced this before. Sure would like to know what they are…Tanis

These appear to be larvae of a fungus gnat (Diptera: Sciaridae), see http://tinyurl.com/l8xa3v6for an image. These likely were feeding either on decaying dead grass or on fungus that was decomposing the grass. Basically nuisance pests.   Ed Saugstad, retired entomologist; Sinks Grove, WV.
