The female will only use her stinger to defend herself. While cicada killers make a loud, buzzing noise and have the striking colors of black and yellow, all this is to discourage predators that might see them as a tasty meal. Cicada killers are only active for about three weeks out of the year digging burrows and laying eggs. Cicadas feed on deciduous trees and damage tree branches by laying eggs in them.ĭuring her lifetime, a female will excavate up to four burrows and gather at least 100 cicadas during the summer. In the chamber with the egg, the female will drag up to three paralyzed cicadas for the young larvae to feed on.Ĭicada killers are beneficial, because they hunt cicadas in the genus Tibicen. In the burrow, the female will lay up to 15 eggs, each one in its own separate chamber. The female in the middle of the summer is busy digging long burrows up to 0.75 inch in diameter and 40 inches in length. Why do cicada killers choose a particular site to live? These solitary wasps prefer well-drained, lighter-textured soils in full sunlight near trees with an abundance of cicadas. The only other wasp that approaches the size of the cicada killer is the European hornet, but their abdomen has more yellow and banding pattern is different. Their distinguishing characteristics beyond their size is the black abdomen with three complex, yellow bands, and the head and thorax are rust colored to dark brown with wings that are a transparent russet. The adult cicada killer is an impressive looking wasp measuring up to 1.5 inches in length. ![]() The stinger on the female wasp is used to paralyze cicadas and the male has no stinger. These have turned out to be the Eastern Cicada Killer (Sphecius speciosus), which is a mild mannered wasp. Over the past couple of weeks, I have been getting many phone calls from people describing giant wasps in their yards.
