These are about as common as most other insects in this area. I also saw a younger, smaller one of the same species at the same time as this one.
This little guy let me pick him up without it curling up into a little ball.
Isopods are an order of peracarid crustaceans, including familiar animals such as woodlice and pill bugs. The name Isopoda derives from the Greek iso meaning "same" and pod meaning "foot". The fossil record of isopods dates back to the Carboniferous period (in the US Pennsylvanian epoch), at least 300 million years ago.
