Widespread throughout England and Wales, with just one 19th century Scottish record to date. Assessments against all criteria give no reason to consider it threatened. However, a reduction in the last ten years is notable against the backdrop of a general significant increase in sawfly recording (Musgrove, 2023).
Very similar to the slightly larger Macrophya albicincta and alboannulata but in ribis the head has dense, coarse punctures above and on the temples, whereas in the two similar species this area is almost impunctate. A wholly black and white species.
Macrophya ribis larvae feed on elder.
