The larvae of Sciapteryx consobrina are highly variable both in colour and black patterning. The ground colour can vary from yellow, grey, green to absolutely black with the complete pattern of the black spots on the one hand to the specimens with the black spots completely missing on the other hand. Likewise, the black head pattern is also highly variable varying from black headed larvae to the quite orange headed larvae with all conceivable intermediate variants between them. The adult sawfly is mainly black in colour, but the abdomen has narrow pale bands. We are grateful to experts John Grearson and Jan Macek of the Czech Republic for their help with identification of this difficult species.
Associated with Moschatel (Adoxa moschatellina) and plants of the Ranunculus family.
