Your letter to the bugman: Hello, At first I thought these creatures were pieces of pond weed. However, on observing them for 10 minutes or so, I see they are ALIVE and they appear to be interacting with each other. The are located in one small part of a garden pond. They appear to have a sucker on one end. I replaced the bug in the photo back in the pond! Thank you for any help in identification.

This is the larva of a Caddisfly, an aquatic naiad that will eventually metamorphose into a flying insect that somewhat resembles a moth. Caddisfly larvae construct a shelter from twigs, shells, pebbles, and other debris, and different species of Caddisflies construct different types of cases.
