But no house can be smaller than a single brick.For a soil invertebrate, however, even a brick fragment could be an abode with plenty of room to share with others.

The other day, when I turned this piece of brick in my backyard over, I encountered a menagerie.
There were 2 species of isopods: the one on the left was probably an Armadillidium nasatum and the one in the middle probably a Porcellio scaber. The bug on the right is probably a true bug (hemipteran), but that's where my knowledge of them ends.
There were 2 species of snails: the small one on top is a Vertigo pygmaeum, while the larger one is a Cochlicopa lubrica. Both are common on and under the rocks in the yard.
Finally, the big woolly caterpillar is a woolly bear, the larva of the moth Pyrrharctica isabella. Those caterpillars are quite common around here, but I don't think I have ever seen the moth itself.
