Prochoreutis sestediana, also knowns as the silver-dot metal-mark is a moth of the family Choreutidae found in Asia and Europe. It was first described by Johan Christian Fabricius in 1776 from a specimen found in Kiel, Germany.
The wingspan is 9–12 mm and the forewings have silver dusting which expands over more than half of the forewing. The fore wings are rather wedge-shaped, with the tip obliquely truncate, brownish; the disc irrorated with minute coppery scales. The costa are dotted with white, the fringe is white, in front and behind dusky. The hind wings are ashy-brown, with an abbreviated whitish striga. There are two generations per year, adults are on wing in May and from July to August. They fly during the day.
The larvae initially mine the leaves of common skullcap (Scutellaria galericulata) and lesser skullcap (Scutellaria minor), later living in a silken web and feeding externally on the leaves. It is found in most of Europe, India, China (Ningxia, Shaanxi), Sri Lanka, Nepal, Russia (Primorskiy kray, Ural, Evropeyskaya chast’, Kavkaz), Japan (Hokkaido, Shikoku), Asia Minor, Zakavkazye, Syria and the Oriental region.

Rare
Under 5% of wildlife watchers report a Silver-Dot Twitcher sighting in Moscow on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 841st most-seen of the 1111 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Silver-Dot Twitcher in Moscow on a given day, so our monthly data shows no clear season.
Only Moscow, in our data
Moscow is the only city on Wallace's Line with enough records to rate Silver-Dot Twitcher sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Silver-Dot Twitcher is recorded against all the insects logged in Moscow (7 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.
