About

The Robin's Pincushion (also known as the 'Bedeguar Gall') is a gall caused by the larvae of a tiny gall wasp, Dipoloepis rosae. It is widespread and common, and can be found developing on the stems of wild roses during late summer, acquiring its reddish colour as it matures in autumn. The grubs inside the gall feed on the host plant throughout the winter and emerge in spring as adults. The adults reproduce asexually and only a tiny number are male.

How to identify

Unmistakeable: the Robin's Pincushion is a spherical, red, fibrous growth on the stems of wild roses.

How can people help

The Wildlife Trusts manage many nature reserves for the benefit of all kinds of wildlife, from bugs to butterflies, fish to Foxes. But these precious sites are under threat from development, intensive agricultural practices and climate change. You can help by supporting your local Trust and becoming a member; you'll find out about exciting wildlife happenings, events on your doorstep and volunteering opportunities, and be helping local wildlife along the way.
