Food Plant: Anemone spp., A.nemorosa and sometimes A.ranunculoides (in N.Europe and Scandinavia)

Mine: April-May

Notes: Forms a blotch mine, with a distinctive frass pattern, when viewed under the leaf. There is normally one mine a leaf. Mine shown on Anemone nemorosa. This is the first species of Pseudodineirini (and of all the sawfly species,except Hoplocampoides xylostei) in the spring. It is a parthenogenetic species and females emerge from the end of March to the middle of April (depending on weather conditions). Oviposition is from the underside of the leaf near the midrib into the distal part of the leaf. It is rarely collected (may be because of its early emergence!). It can be found in meadows along rivers and ponds. Larvae are attacked by Ichneutes brevis (high rate), a
braconid species. The larva is a pale colour and has pale legs and a brown head. There is some sclerotization of the prothorax (as seen in the ventral view of the larva above). The bottom photo shows a ventral projection from the rear of the larva.
