Sphecius speciosus / Hymenoptera
These wasps were active in the sandbox on the kindergarten playground at my school in August. It was very hard to convince the administration not to spray the underground nests since some of the kids were totally freaked out at the sight of these huge wasps emerging from the ground! They are not aggressive to people, only cicadas. I tried to explain it would be more dangerous to spray large amounts of insecticide in the sand than just have the children avoid the sandbox for a few weeks!
