Aglaostigma fulvipes

Aglaostigma fulvipes is one of two species of Aglaostigma in Britain and Ireland. This species occurs later than aucupariae and is perhaps less frequent. Aglaostigma fulvipes is blackish with a red girdle but is marked with creamy-yellow laterally and ventrally and on the head (often extensively in males but much less so in females).

Larvae feed on bedstraws. Females lay the eggs into a stem and often cut the stem partially through just above the laying site.
