Willow Gall Sawfly - Pontania pedunculi
Pontania pedunculi is a sawfly that causes a gall on certain species of Willow: Salix capraea (Goat Willow), Salix cinerea (Grey Willow) and Salix aurita (Eared Willow). The gall is commonly seen but the adult sawfly rarely so. The gall is generally pea-shaped, starting green but becoming red as it matures. It is hairy and only found on the underside of the leaf.
