Tenthredo livida


12-15mm. It has a conspicuous white 'mouth' and white tips to its antennae. It is really variable in colour, sometimes all black, but other forms with varying amounts of red, sometimes with yellow on the middle tergites. The white marked antennae together with the white and brown stigma in the forewing are distinctive and help with the identification.

Similar Species

Other species also have the white banded antennae and a white 'mouth'. T. livida can be distinguished by having two-tone stigma - the apical two thirds brown and the basal third pale.

T. ferruginea has a yellowish brown stigma and usually has white on the thorax and over the eyes.

T. balteata has a black or dark brown stigma.

T. colon females have hind femurs with the distal third black in colour. Also the teeth on the basal part of the saw are relatively flat and rounded.

T. semicolon females have only the tip of the femur black. At the base of the saw the teeth are much sharper and triangular in shape.
