About the Willow Redgall Sawfly
Euura proxima is a species of sawfly belonging to the family Tenthredinidae (common sawflies). The larvae feed on the leaves of willows (Salix species), creating galls.

The larvae have a darkened head, typically seen as they increase in maturity. Once they emerge from the gall, they form a cocoon. This cocoon takes on soil particles and leafy matter, having a fibrous texture. Overall, it is described as being cylindrical in shape with a golden brown color, the thickness depending on the developmental stage of the specimen.
The body of adult E. proxima is mostly black with a brown hue, the legs being a lighter, reddish-brown tone. A distinctive feature of this species is its thread like antenna which have shorter antennomeres compared to other similar species. This species is a part of Hymenoptera, which can be identified through multiple facets. For example, Hymenoptera have four membranous wings, mandibulate mouthparts and a true ovipositor. Mandibulate mouthparts are identified by multiple... Wikipedia →
