About Collita griseola (Hübner, 1803)
Collita griseola, commonly known as the dingy footman, is a moth species belonging to the family Erebidae. It was first described by Jacob Hübner in 1803. This moth is distributed across Europe, and North and South-East Asia. Its wingspan measures between 32 and 40 mm. Adults fly from May to August, with the timing varying based on their location. The larvae of this species feed on lichen. Between 1968 and 2007, this species experienced a dramatic increase in population abundance in Britain, a trend shared by a number of other moth species whose larvae feed on lichens and algae. Originally, in Britain, the species was restricted to southern fens and marshy areas. It has since spread northwards, and now occurs in a wide range of habitats, including gardens.
