First, a thank you to Goldfinch4 & Cwhitt for helping me out this morning.
Yesterday, I noticed a full on explosion of spot marks all over most of my sempervivums. Looking at them more closely, they are more than spots they are indentations. See pic.
Goldfinch4 suggested snails or slugs. I just pulled up a few rocks and found this tiny guy; see pic. Is he they likely culprit? If so, who is he & how do I get rid of him?
Again, thank you for your help.
