Field Notes

Description:

Rose Bedeguar Gall, AKA Robin's Pincushion Gall or Moss Gall, growing on a rose plant Mount Pisgah, Oregon. Apparently it not a flower, but rather a chemically induced distortion of an unopened leaf axillary or terminal buds caused by the parthenogenetic hymenopteran gall wasp.

No problem! These galls are often crazy-looking like this one. Those flowers are also pretty awesome!

Oh wow, I would have never guessed that one. I had no idea such a thing existed. Thanks for the lesson! I assumed it to be a flower, since it looked similar to some of the flowers we had in Hawaii: http://www.projectnoah.org/spottings/283156122 http://www.projectnoah.org/spottings/250616004

The plant is a rose of some sort (Rosa) but what you are looking at is a gall made by a wasp (probably Diplolepis rasae) http://en.wikipedia.org/wiki/Diplolepis_rosae
