18 May Mud Wasps
I found these nests in my shed and thought many of you have probably seen them and wondered what they are. These nests are made by mud wasps. Mud wasps are solitary insects that will capture a spider or caterpillar, paralyze it, lay an egg on it and encase it in mud. The larvae will then hatch and have the prey for their first meal (yummy). Mud wasps are not aggressive and do a pretty good job of lowering the population of some harmful caterpillars. As you can see the adult emerges from the nest and you can see where a couple more wasps will come out. The mud can be unsightly on siding and may cause staining.
