Braconid Wasp Cocoons On A Hornworm
When I first saw this Hornworm on my tomato plant I didn’t know what the cocoons on its body were. After doing research I discovered that a Braconid Wasp deposits her eggs inside the hornworm caterpillar’s body. The Wasp larvae develop and feed inside the caterpillar. The Braconid Wasp larvae chew their way out of their host and spin silk cocoons on the caterpillar. The tiny adult wasps emerge from these cocoons a short time later.
Note: Hornworms are the larval stage of the Sphinx Moth
