Collita griseola, the dingy footman, is a moth of the family Erebidae. The species was first described by Jacob Hübner in 1803. It is found in Europe and North and South-East Asia. The wingspan is 32–40 mm. The moth flies from May to August depending on the location.
The larvae feed on lichen. This species has shown a spectacular increase in abundance in Britain during the period 1968 to 2007, like a number of moth species with larva that feed on lichens and algae. In Britain it was originally limited to southern fens and marshy areas, but has since spread northwards and now occupy a variety of habitats, including gardens. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Dingy Footman is recorded against all the insects logged in Birmingham (8 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
