Observation notes: This little guy is 1 inch long. He can go pretty fast, like half way around the house. It moves almost like an inch worm. For 2 mornings in a row it has been right next to our back sliding glass door early in the morning. Both mornings, it was sunny and about 64-69 degrees. Our house is stucco. He stayed on the house. He went along the back, to the right(north) around the corner and all the way along the north side of the house. Lost track of him then. I think it came from the lilac bushes that lean against the SE prt of the house.

Coordinator notes: This is the caterpillar of the Western Grapeleaf Skeletonizer moth. It sounds like the one you found got seperated; they usually congregate in large groups to feed on members of the grape family.
