Description

Arge pagana can reach a length of about 1 cm. Wings and veins on the wings are black, often with blue metallic sheen. Pronotum and legs are also black. Its most conspicuous feature is a large rounded yellow abdomen. It has a black head and thorax and the legs are largely black. Larvae reach about 25 mm and are pale green with black dots and a yellow head.[5]

Biology

The eggs are laid on roses. Larvae appear in early summer and reach full size by the end of July.[5] The larvae are gregarious and live in colonies feeding on rose leaves (Rosa species, Rosa acicularis).[6]

The pupal period is very short. Adults feed on nectar and pollen from Tanacetum vulgare and Heracleum sphondylium. During the warmer years there may be two or, rarely, three generations.
