I saw these little white “things” on my boxwood bush and thought for a split second something had flowered. Upon closer inspection this was a large green caterpillar with a serious looking spike on its tail. I wondered if these are babies attached to her? She was VERY AGGRESSIVE when I tried to handle her. I carefully placed her back on the bush after these pics!

Your caterpillar is a Hornworm in the family Sphingidae, and as the caterpillar is a larva, it is not able to reproduce until it becomes a winged adult moth. This Hornworm has been parasitized by a Braconid Wasp, and the white “things” are the wasp pupae. The larval Braconid Wasps have been internally feeding on the Hornworm, which is eaten alive. The adult Braconid Wasps will soon emerge and the Hornworm will die before becoming an adult. We have not been able to identify the species of Hornworm and we cannot find any information on Hornworms feeding on Boxwood.
Thank you for all the wonderful information! That’s so sad that the caterpillar was being eaten alive 🙁
I’ve lived here almost 13 years and this is the first time I’ve seen one of these.
Thank you for all you do!!
