Athalia circularis - Ringed Tigress
Recorded widely across all of mainland Britain. There is suspicion that Athalia circularis maybe a complex of species, each with a narrower larval food plant range. The middle tibia maybe ringed with black apically but the fore tibia are always entirely yellow. The length of the inner tibial spur of the hind leg is greater than the length of the fourth tarsomere of that leg. Vein C of the forewing is yellow for no more than the basal third. [Note that the similar Athalia longifoliae is present on the near continent and the two can only be separated by the male genitalia.]
Larvae feed on a variety of herbaceous perennials including ground ivy, plantains and speedwells and often in wet places.
