About Oligia fasciuncula (Haworth, 1809)
The forewing of Oligia fasciuncula is bright rufous, with deeper coloring in its median and terminal areas. Its inner and outer lines are white, with the outer line being particularly white on the inner margin, and its stigmata are slightly paler. The hindwing is blackish fuscous, with a whitish fringe. There are several recognized aberrations and forms of this species. The aberration ab. cana Stgr. is much paler than the typical form, especially in the basal and outer areas, has an overall olive drab coloration, and has no rufous tint. pallida Tutt is an extreme variant of ab. cana, which has a hoary-colored median area in addition to hoary basal and outer areas. suffusa Tutt, collected from Armagh, Northern Ireland, is greyish black, with all faint markings, and somewhat resembles aethiops Haw. A Scottish form, ab. brunneata, is browner, particularly in the lower half of the median area. As recorded in 1914, this species is only found in Western Europe, including Britain, Denmark, Holland, Northern France, and Spain. Its considerably restricted distribution is a strong reason why it is not considered a form of strigilis.
