Post update: Friend! These appear to be Soldier Beetles, Family Cantharidae, also known as Leatherwing Beetles. Thanks Angela, of Angela's Northern California Garden Blog. According to the link she left me, soldier beetles prey upon aphids, caterpillars, grasshopper eggs and beetle larvae, among other insects around the garden. How to attract: Since some soldier beetles feed on nectar, you may be able to attract them with flowering plants. (Parsley nectar seems to be quite agreeable to them.)
What are these bugs that like to hang out on the parsley? They don't seem to damage the parsley, but will I regret having them around later?
