Your letter to the bugman: These are about an inch long, and are aggressively moving through my garden. May be responsible for some painful skin reactions, but unconfirmed. Any idea what they are, and what they’ll turn into?

These are Stinging Slug Caterpillars in the family Limocodidae and we have previously identified them as Latoia vivida. Stinging Slug Caterpillars should be handled with extreme caution as they are capable of delivering a painful sting.
