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 →

With luck
About 10% of wildlife watchers report a Dingy Footman sighting in London on a given day, based on 67 verified sightings from GBIF citizen-science data. It is the 398th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report a Dingy Footman in London on a given day, against under 5% in September to June, the lowest months.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Dingy Footman sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 8 cities where we can rate Dingy Footman sightings, London ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Liverpool (United Kingdom, about 10%) and Rotterdam [The Hague] (Netherlands, about 10%).
Same family: Erebidae
The closest relatives of the Dingy Footman that you can see in London (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Jersey Tiger (about 40%), Cinnabar Moth (about 30%) and Spongy Moth (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dingy Footman is recorded against all the insects logged in London (67 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.
