Pammene argyrana is a species of moth belonging to the family Tortricidae. It is native to Europe. The wingspan is 10–13 mm. The forewing has a white or brownish-white spot at the dorsal edge. The colour of the hindwings is characteristic: brownish white with sharply delineated brown areas in the posterior part and at the apex. Meyrick describes it - The forewings are fuscous, sometimes ochreous- tinged, irregularly marked with black, costa strigulated with black and white; three streaks from costa and margins of ocellus leaden - metallic; sharply angulated edge of basal patch and central fascia darker, separated by a somewhat pentagonal white dorsal blotch more or less strigulated with blackish; a suffused blackish spot before apex. Hindwings fuscous, in male basally whitish, with terminal and broader dorsal blackish fascia, in female posteriorly darker fuscous. The larva is pinkish-white, sharply ringed with white; spots red; head brown; plate of 2 whitish or grey, posterior edge blackish
Like Pammene giganteana, this species has larvae that develop in galls made by Cynipidae on Quercus. The adults fly in April–May, mostly at night, they often rest in a bark crack during the day. Wikipedia →

Rare
Under 5% of wildlife watchers report a Black-Bordered Piercer sighting in London on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1300th 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.
April
In that month about 10% of wildlife watchers report a Black-Bordered Piercer in London on a given day, against under 5% in May to March, the lowest months.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Black-Bordered Piercer sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Black-Bordered Piercer is recorded against all the insects logged in London (6 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.
