Thanks, Jenn! That is very interesting. Have you ever had it eat crickets or any other commonly available feeder insects?
Oliverian- lots of things eat slugs that don't eat insects. Neat that you've seen it emerge with a spider though. Despite being easier to find, bugs are not commonly eaten by many snakes. Lots of snakes have very picky diets- I'm sure that it is easier to find bugs than many other things, but that doesn't mean that they snakes will take them.
