The Cicada Killer Wasp is BIG! We have them all along the dirt road leading to the cabin. Click on the picture to see it larger.
They dig long tunnels underground, often several feet long. They capture and paralyse Cicadas and lay eggs on them. When the young hatch they feed on the still living Cicada. Here is a burrow entrance on our road.
The pictures were taken last year. I have not been able to get a decent picture of them this year.
