Tenthredopsis coqueberti
One of six species recorded in Britain. A difficult group to identify due to the extreme variability in colour. This group is likely to undergo taxonomic changes in the future. Males of this species can be distinguished by the penis valves which have needle-like projections that are shorter than the hind femur inner apical spur. Males also lack a peripheral vein on the hind wing. Females have a black abdomen with a red girdle.
Larvae feed on grasses.
