Last Friday night around 11:30 in my backyard a discarded banana peel that had ended up in the flower bed instead of the compost pile was the focus of attention of several species of local invertebrates. Among them were slugs, including these that were probably Arion subfuscus. Also notice the small spider near the top lefthand corner.
Many isopods had also joined the feast. In this picture the one on the left may be an Armadillidium nasatum, while the one on the right may be a Philoscia muscorum.
At one point I noticed a black beetle within the folds of the banana peel. I had just gotten the camera ready, when it surfaced, briefly "sampled" one of the slugs and then disappeared.
