Cylindrical holes in the ground.
We have a number of perfectly cylindrical holes drilled in the dirt next to a Holly tree. In a few instances, there appears to be a a neat mound of dirt above the ground, looks almost like a small bees next. The holes look similar to the holes that carpenter bees drill in wood. My neighbor says that wasps and hornets burrow in the ground like this. We have lived here for decades and never seen anything like this. What are we dealing with?? Thank you.

Send us photos of the holes in the ground so we can see what you may be dealing with.
Just checking to make sure you received the photos I sent. Thank you.
Our entomologist looked at your photos and says these are holes from emerging annual cicadas. They look like this when they emerge during wet weather.
