Phyllonorycter corylifoliella, the hawthorn red midget moth, is a moth of the family Gracillariidae. It is found in all of Europe. The wingspan is 8–9 mm. The forewings are reddish-ochreous, posteriorly or sometimes almost wholly suffused with blackish-grey blotches; a slender white median streak from base to near middle, with a marked sinuation downwards; a slender oblique white streak from the middle of costa, and another from the middle of dorsum; sometimes a whitish tornal dot and anteapical strigula. Hind wings are grey or dark grey. The larva is pale yellowish; dorsal line green; head pale brownish.
Adults are on wing in May and again in August in two generations. The larvae feed on Amelanchier lamarckii, Amelanchier ovalis, Betula pendula, Betula pubescens, Chaenomeles japonica, Cotoneaster nebrodensis, Crataegus laevigata, Crataegus monogyna, Cydonia oblonga, Malus domestica, Malus sylvestris, Mespilus germanica, Prunus avium, Pyrus amygdaliformis, Pyrus communis, Sorbus aria, Sorbus aucuparia, Sorbus domestica, Sorbus torminalis and Spiraea species.

Rare
Under 5% of wildlife watchers report a Hawthorn Midget sighting in London on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 895th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September and October
In those months about 10% of wildlife watchers report a Hawthorn Midget in London on a given day, against under 5% in November to August, the lowest months.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Hawthorn Midget sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Phyllonorycter
The closest relatives of the Hawthorn Midget that you can see in London (genus Phyllonorycter) are Firethorn Leafminer (about 10%), London Midget (about 10%) and Nut Leaf Blister Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hawthorn Midget is recorded against all the insects logged in London (20 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.
