Description
editThe 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 10 millimetres (0.39 in) to 15 millimetres (0.59 in) long by approximately 5 millimetres (0.20 in) 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
editListon 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]
