A few days ago, upon daily inspection of my tomato plants, I saw this uninvited guest:
After screeching and gagging, I ran to my computer to investigate. I found out that this is the larvae of a tomato hornworm that has been parasitized with wasp eggs. Basically, a wasp layed eggs on this moth larva, slowly destroying it. The wasps will kill the hornworms when they emerge from the cocoons and will seek out other hornworms to parasitize...pretty gross but pretty amazing!
