Euura weiffenbachiella is a species of sawfly belonging to the family Tenthredinidae (common sawflies). The larvae forms galls on creeping willows (Salix repens). E. weiffenbachiella is one of a number of closely related species which is known as the Euura atra subgroup.

Description

The shape of the gall is variable, probably depending on where the egg is laid;[2]

  • it can develop on one side of the shoot, causing it to bend and look similar to a miniature gall of E. amerinae, or
  • it can be spindle-shaped with the shoot remaining straight measuring {{convert|10|mm}} to {{convert|15|mm}} long by approximately {{convert|5|mm}} wide.

Found on creeping willow (S. repens) and S. rosmarinifolia.[2]

Other similar looking species in the Euura atra subgroup are,[2]

  • E. atra found on white willow (Salix alba) and crack willow (S. fragilis).
  • E. auritae found on eared willow (S. aurita)
  • E. myrtilloides found on swamp willow (Salix myrtilloides)
  • E. salicispurpureae found on purple willow (S. purpurea)

Distribution

Liston et al. records the sawfly from central and northern Europe, and east to Yakutia.[2] Redfern et al. records the gall from Great Britain (Scotland) and Ireland.[3]
