Arge pagana is a sawfly in the family Argidae. It is known by the name "large rose sawfly" although the related species Arge ochropus is also known by this name.
Subspecies
- Arge pagana pagana (Panzer, 1798) [2]
- Arge pagana stephensii (Leach, 1817) [3] (British Isles)
Distribution
This species can be found in the Palearctic ecozone.[4]
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 conspciuous 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.
