Strangeness

with 37 comments

This is likely Rosa carolina but the fruit are distorted because of the Spiny rose gall wasp (Diplolepis bicolor).

At Illinois Beach State Park on June 9th I came across the unusual red things shown in today’s photograph. After I submitted the picture to the Illinois Native Plant Society, Rachel, who is the organization’s secretary, e-mailed me back to say that the plant is likely Rosa carolina and that the spiky red things are galls created by the spiny rose gall wasp, Diplolepis bicolor. Pretty strange, huh?
