I’d love info on these delightful little visitors as we seem to have a family who lives/visits our yard every spring. I cannot leave the house.
The Cicada Killers, Specius speciosus and Sphecius grandis, are large solitary wasps that often live in colonies, hence your comment about the family situation. They produce one generation a year, and you are being visited by the offspring of the previous year’s visitors. The wasps are large, nearly 1 2/3 inches in body length, with a much larger wingspan, and they feed on nectar and pollen. Mating males are sometimes aggressive, and females will deliver a nasty sting if provoked. It is the female who kills the cicadas. She hunts for them on tree trunks after digging a burrow. She stings the cicada, paralyzing it, then flies back to her burrow with the now immobile, yet living food source for her brood. Each burrow contains one or two cicadas, and when the solitary egg hatches, the larva has a fresh food supply.

Thank you so much!! My exterminator was totally clueless (so I had to capture one and look online to find out about it – that’s how I knew it’s name) but I’ve now that I’ve seen them in my yard I’ve seen them around a lot more – don’t know if it’s a case of knowing what I’m looking for or if they’re really settling in around South Orange, NJ, but I do appreciate your great information on them. Poor cicadas – darn that must hurt! I’d noticed how aggressive the males are – especially if you fill up their burrow and they can’t get back in ;)Best,
