Description
Mating couple: the female to the left, the male to the right with the wings spread out

Macrophya montana can reach a length of 8-12mm.[3][4] This species shows an evident sexual dimorphism.

The females are recognisable by black and yellow markings. The head is black with yellow clypeus and labrum. On the abdomen the first tergite is completely yellow, the fifth and sixth are broad, yellow, interrupted in the middle. On the seventh, sometimes also on the fourth, there are small yellow spots on the sides. Also the ninth tergite is yellow. These markings are absent on the abdomen of the males, that are completely black.

In the females the legs are predominantly yellow with black markings. In the males the first two pairs of legs are pale yellow, while the hind legs are mainly black, but the tips of the tibias and part of tarsi are white.

Biology

The adults of this sawfly can mostly be encountered from May through July.[3] Adults mainly feed on pollen and nectar, especially on Heracleum sphondylium,[4] but they feed also on honeydew and small insects.[3] The larvae are monophagous and develop on the leaves of blackberries and raspberries (Rubus fruticosus).[3][4]

gollark: It's worse than potatOS - I think it has at least a hundred times more bugs.
gollark: You see, windows bad.
