Rotund disk snails

In a walk to my local cemetery I found this group of disk snails, Discus rotundatus, under a decaying branch. They are small snails up to 7 mm in diameter, with a lovely ribbed shell with reddish banding. It feeds on algae, fungi and decaying vegetation in damp and shady places and shelters in groups under bricks, rocks, logs and at the base of tree trunks in dry weather.

Beautiful snails. We have similar woodlice to the one in your photo here in New Jersey. We call them "fast woodlice".

Thank you for commenting Sara. Probably both sp. now in USA imported from Europe. They probably easily ride timber and become established. The fast woodlice are not so fast in winter, they are a bit sluggish in cold conditions, fortunately for me.
