Arge cyanocrocea
Arge cyanocrocea, the bramble sawfly, is a species belonging to the family Argidae subfamily Arginae. The adults grow up to 7–8 millimetres (0.28–0.31 in) long and can be encountered from May to July, feeding on pollen and nectar of several Apiaceae species (Aegopodium podagraria, Meum athamanticum, Heracleum sphondylium, etc.), Euphorbiaceae species (Euphorbia spp.) and Asteraceae species (Tanacetum vulgare). The larvae of this species look like caterpillars, but they have five pairs of prolegs, while caterpillars have four pairs. The larvae feed on the leaves of brambles (hence the common name), mainly blackberry (Rubus fruticosus), raspberry (Rubus idaeus) and great burnet (Sanguisorba officinalis).
