This singular-looking caterpillar is frequently found on plum-trees, devouring the leaves; it is also found on maple, oak, and probably other trees, and on strawberry-vines. It is about seven-tenths of an inch long (see Fig. 176), of a grayish color, with dusky and blackish streaks. On the hinder part of the fifth segment are two long, curved, fleshy horns extending forward, and on the sixth segment there is a similar pair curving backwards. The head is spotted with brown. There are two short brown tubercles on the posterior part of the fourth segment, and two small gray warts on each of the segments behind, those on the eleventh being most prominent. It may be found during tlie first half of June, and sometimes later. During the latter part of the month it constructs a slight cocoon composed of pieces of leaves fastened together with sillvcn threads, and within this enclosure changes to a reddish-gray or pale-brown.
