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.
