Euura auritae is a species of sawfly belonging to the family Tenthredinidae (common sawflies). The larvae forms galls on willows (Salix species). It was first described by Jens-Peter Kopelke in 2000. E. auritae is one of a number of closely related species which is known as the Euura atra subgroup.
Description
[edit]The gall is an elongate swelling that tapers into the young shoot. It is 10 millimetres (0.39 in) to 15 millimetres (0.59 in) long by approximately 5 millimetres (0.20 in) wide. The bark around the gall is smooth and contains one larva which has three dorsal annulets on the third abdominal segment, and a suranal plate without pseudocerci.[1][2] Pupation is probably in the gall.[1]
In Britain the gall has been found on eared willow (Salix aurita).[2] Elsewhere it has also been found on grey willow (S. cinerea), downy willow (S. lapponum) and (S. starkeana).[1]
Other similar looking galls in the Euura atra subgroup are,[3]
- E. atra found on white willow (S. alba) and crack willow (S. fragilis).
- E. salicispurpureae, found on purple willow (S. purpurea)
- E. myrtilloides found on swamp willow (Salix myrtilloides)
- E. weiffenbachiella, found on creeping willow (S. repens) and S. rosmarinifolia
Distribution
[edit]Euura auritae has been recorded in central and northern Europe to Finland, Norway and Sweden. Also Czech Republic, Great Britain and the Netherlands.[1][2][3][4]
