Summary[edit]

Description
English: Rose bedeguar galls An example of the rose gall, more often known as a robin's pincushion. The gall is created by the plant in response to an attack by the larvae of a gall wasp (Diplolepsis rosae) which then live in and feed on the resulting formation until emergence. In fact a recent study revealed that up to 17 different species had been found to inhabit bedeguars, some being inquilines - that is, larvae that use the gall without having formed it themselves - as well as parasites that feed on the larvae in situ.

For information on the rose gall research project see http://www.british-galls.org.uk/bedeguar.htm

The bedeguar is not of itself harmful to the plant.
