Stigmella plagicolella is a moth of the family Nepticulidae described by Henry Tibbats Stainton in 1854. It is found in all of Europe (except Iceland and Norway) and the Near East. The wingspan is 4–5 mm. The thick erect hairs on the head vertex are orange and the collar dark bronze fuscous-white. Antennal eyecaps are whitish. Forewings are shining deep purplish-bronze; a shining whitish fascia beyond middle; apical area beyond this dark purple-fuscous Hindwings are grey.
Adults are bivoltine and are on wing from May to June and again in August. Egg The egg is laid on the underside of a leaf in June or August, usually near the midrib. Larva The larvae are pale, whitish yellow with a reddish brown head. They mine the leaves of their host plant, initially in a slender corridor with a wide uninterrupted frass line. After a moult this corridor abruptly widens into a blotch. Stigmella plagicolella feed on the following plants, apple (Malus domestica), apricot (Prunus armeniaca), wild cherry (Prunus avium), cherry plum (Prunus cerasifera), Prunus cerasifera var. pissardii, plum (Prunus domestica), Prunus domestica insititia, mahaleb cherry (Prunus mahaleb), Chinese plum...

Rare
Under 5% of wildlife watchers report a Scrubland Pigmy sighting in London on a given day, based on 16 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 Scrubland Pigmy in London on a given day, against under 5% in November to August, the lowest months.
2nd of 2
Of the 2 cities where we can rate Scrubland Pigmy sightings, London ranks 2nd at under 5%. The best odds are in Budapest (Hungary, about 10%).
Same genus: Stigmella
The closest relatives of the Scrubland Pigmy that you can see in London (genus Stigmella) are Golden Pigmy (about 10%) and Scarce Maple Pigmy (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Scrubland Pigmy is recorded against all the insects logged in London (16 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.
