The genus is now placed in the monotypic family Scythropiidae., but was previously placed in subfamily Scythropiinae either in Plutellidae or Yponomeutidae.
Initially (in 1796), Hübner had misidentified the grass moth Eudonia lacustrata – much larger and only distantly related, but somewhat similar in color and pattern – as Linnaeus' Phalaena crataegella. Similarly, a junior synonym of this species, Tinea cornella, has frequently been misapplied – and sometimes still is even today – to the fairly closely related apple blossom tineid.
Scythropia crataegella is a small moth is widespread almost all over Europe; it is absent from Great Britain north of The Lake District, and has also not been recorded yet on Iceland and Ireland (where it is probably genuinely absent), in Portugal (where it may be absent), and in Slovenia (where it probably occurs but has not been found yet, as its range...

With luck
About 10% of wildlife watchers report a Hawthorn Moth sighting in London on a given day, based on 83 verified sightings from GBIF citizen-science data. It is the 390th 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.
May to August
In those months about 10% of wildlife watchers report a Hawthorn Moth in London on a given day, against under 5% in September to April, the lowest months.
Among the best
Of the 4 cities where we can rate Hawthorn Moth sightings, London ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Liverpool (United Kingdom, about 10%).
Same family: Yponomeutidae
The closest relatives of the Hawthorn Moth that you can see in London (family Yponomeutidae, Ermine Moths) are Bird-Cherry Ermine (about 10%) and Spindle Ermine Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hawthorn Moth is recorded against all the insects logged in London (83 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.
