Parasitism of a Caterpillar


I found this cryptically colored and lumpy caterpillar and when I began to take pictures of it, I realized that a black egg deposited on its back was beginning to hatch and that the larva was going to burrow into the caterpillar. Picture 2 shows the black egg on the surface of the back. Pictures 3, 4 and 5 show the tiny white larva emerging from the egg. Picture 6 is a closer view of the larva, showing its tiny head capsule (its exactly in the center of the picture). The caterpillar was wandering, preparing to pupate, so I brought it home to see what happens.
