The larvae of the midge Dasineura viciae cause galls to form on Common Vetch (Vicia sativa) and Bush Vetch (Vicia sepium) The leaflets swell to form pod like galls which may form dense clusters ranging in colour from green to red. The swollen areas contain small larvae which are pale orange or pale lemon in colour. The galls are seen more easily than the causer.
Similar galls are formed on Vicia cracca, Ervum tetraspermum or other species of Vetch or Tare

Rare or under recorded in Leicestershire and Rutland. The record from Broughton Astley on 25th June was the first for VC55.
