While working in our FFL demonstration garden, we came upon a Cicada Killer Wasp dragging a Cicada across the ground.
The Cicada Killer had already killed one Cicada and put in into the small hole of a utility box cover. It was piercing the second Cicada and dragging it to the same hole. Cicada Killers pierce the Cicadas and lay their eggs inside of the Cicada. Normally they dig a hole in the sand where they bury the Cicadas, but this one was making her nest elsewhere.
Here, you can see the two Cicadas, in the "nest". The Cicadas Killers will then hatch out of the Cicada and feed on it's decaying body. Cicada Killers are considered "good bugs" because they destroy the Cicadas that feed on plants. They are not aggressive and do not normally sting. See more information on Cicada Killers here.
