My Dad found a caterpillar on a plum tree during the last days of summer (August 27th). It had a red head with black antennas. At first glance they appeared twice as long as they really were because of all the long black hairs on them. The caterpillar also had four white clumps of hair sticking up along the upper part of its back. Starting at the second hairy white clump there was a yellow stripe on either side running down its back. It also had white clumps of hair around every leg. Overall it had a light green body. Dad thought something so strange looking might not be good for his plum tree so he brought it inside and asked us four kids to figure out what it was.
