Braconid Wasp on Tomato Hornworms

Don't make the same mistake I did of killing these hornworms with cocoons on their backs. The cocoons are of the beneficial braconid wasp.

I've seen these little wasps, less than half an inch long, flitting about in the garden but never knew they were so beneficial. They feed on flowers with small bracts like herb flowers. No wonder I have so many of them around. I have lots of herbs. The wasp is not harmful to humans and does not sting. the female braconid wasp lays it's eggs inside the tomato hornworm and the larvae eat their way out and form cocoons and eventually turn into more braconid wasps.

Thanks for reading and for all your comments.


  1. I didn't know. No tomatoes this year, or herbs.

  2. Hi Joanne, thanks, I didn't know either, first time I have ever seen those white cocoons on a hornworm.

  3. Cruel as nature can sometimes be, she is amazing.


I love suggestions, questions, critiques, thanks for your comment
