Acompsia cinerella
In 3 days ~10%
Acompsia cinerella, the ash-coloured sober, is a small lepidopteran species of the twirler moth family (Gelechiidae). It is the type species of the genus Acompsia, once assigned to the subfamily Anacampsinae but generally placed in the Dichomeridinae. The species was first described by Carl Alexander Clerck in 1759.
This species can be found in most of Europe, except for Portugal and Iceland. These moths inhabit a variety of areas, preferably with rich vegetation or bushes. Acompsia cinerella has a wingspan of 16–19 mm. These moths have long upwardly-curved labial palps. The forewings show a brownish colour, without any marking. This species is rather similar to Helcystogramma rufescens. Meyrick describes it - Forewings rather light greyish-brown; stigmata sometimes faintly darker. Hindwings grey.
There are two generations per year, as it is a bivoltine species. Adults are on wing from May to September. The larvae feed on moss present on trunks of broad leaves trees, often at the base of the tree. Erstbeschreibung: Clerck, C.

Rare
Under 5% of wildlife watchers report an Ash-Coloured Crest sighting in Moscow on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 992nd most-seen of the 1111 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Ash-Coloured Crest in Moscow on a given day, so our monthly data shows no clear season.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Ash-Coloured Crest sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
3rd of 3
Of the 3 cities where we can rate Ash-Coloured Crest sightings, Moscow ranks 3rd at under 5%. The best odds are in London (United Kingdom, about 10%) and Helsinki (Finland, under 5%).
GBIF citizen-science records
It is estimated from how often the Ash-Coloured Crest is recorded against all the insects logged in Moscow (5 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.
