This is a new species for me. Found it on Queen Anne's lace, summer 2015. I have found so many new insect species this year and learned a lot. The female will make a mud nest with several cells. In each cell she will put 10 or so paralyzed spiders then lay an egg on the last spider and seal the cell with the egg and plenty of food for the baby when it hatches. When she has done with this each cell, she adds more mud to cover the entire nest.
