I reached in and scooped him out, but noticed that he was still dragging 4 ants, like cement shoes. No matter how fast he tried to run, there was and ant or two holding him back.
I pulled off two of them, but the two on his antenna were a bit more difficult. They had his antenna in their pincers and I was afraid that I would pull off his antenna if I tried to remove them.
Then I noticed that the beetle was using his legs to scrape them off himself.
Eventually he got free.
