Holy Bug

As I was opening some hips from a wild white rugosa found on the seashore I noticed that many of the seeds had a single hole in them and also a spidery web with small round eggs(?)imbedded within the hip. Does anyone know the culprit?

I wrote a note about the probable hole maker in a recent RHA newsletter. You are a member and get the newsletter? If not, you need to be.

I would suspect that they were infected by a chalcid wasp, see:


We may see more of this in the future as the rose seed chalcid is proposed as one of the “weapons” to use in the fight against wild multiflora roses.
