5615 I found this larvae in a mud tube under my fascia on the brick wall. I have these tubes at the front and the side of my house. At the front it looks like spiders but not sure at the side. I do get a lot of wasps around my house in July and August. This was taken Feb 20 2016 in Rockwood Ontario. Thanks Paul.
This is a mature larva/prepupa of a mud-dauber, a wasp in the family Sphecidae. It likely had consumed all the provisions (usually living but paralyzed spiders) that its mother had placed in the mud ‘nest’ for it. Ed Saugstad, retired entomologist; Sinks Grove, WV.
