I found 5 of these on the outside of my kitchen trashcan today, and later brushed one off my neck- I have been working in the veggie garden, and I think they came in possibly on carrot tops, etc. The other day I saw one on a tomato or cucumber leaf- don't remember. I checked all my fresh veggies in the pantry near the trashcan- none there. I don't think it is a threat, but would like to know what it is. Thanks-
