Similar species Phyllonorycter sorbi and Phyllonorycter mespilella are close relatives and require genitalia examination to tell apart, alternatively collect the pupa from the food plants. Ovum Eggs are laid on the underside of a leaf.

With luck
About 10% of wildlife watchers report a Common Thorn Midget sighting in Liverpool on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 344th most-seen of the 632 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.
October
In that month about 20% of wildlife watchers report a Common Thorn Midget in Liverpool on a given day, against under 5% in December to July, the lowest months.
Only Liverpool, in our data

GBIF citizen-science records
It is estimated from how often the Common Thorn Midget is recorded against all the insects logged in Liverpool (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.
