Look at him!!! I caught him on Sunday, while hiking in the mountains around Simi Valley.
I feed him a worker and of a wild Nylanderia vividula colony from my backyard every day, and he pulls them underground and I hope he is feeding on them.
This was his hole two days ago:
Here is his hole today, notice it got steeper. Also I do not put a lid on him so the dirt he flings out gets all over my table, but it is funny.
If you do not know what this is, it is an ant-lion.
