Host plants Only Ribes uva-crispa has been unequivocally recorded (Taeger et al. 1998). Genetics COI Based on 4 specimens, maximum within-species distance is 0.76% and the nearest neighbour, diverging by a minimum of 3.5%, is Euura leucotrocha. Nuclear Based on 3 specimens, maximum within-species distance is 0% (0% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.67%, is Euura ribesii. Distribution and material examined Palaearctic. Specimens studied are from Croatia, France, and Germany.
