Hypsopygia glaucinalis is a moth of the family Pyralidae. It is sometimes placed in the genus Orthopygia either alone or with a few other species. Being the type species of Orthopygia, as soon as O. glaucinalis is placed in Ocrasa (as is done here) "Orthopygia" is abolished. To further complicate matters, Ocrasa is now mostly treated as a synonym or subgenus of Hypsopygia.
It is native to the European continent. The wingspan is 23–31 mm. The forewings are brownish-grey, on costa purplish; median part of costa dotted with yellow; lines pale ochreous, nearly straight, stronger and yellower on costa.
Hindwings grey; two fine whitish approximated lines, first twice sub angulated, second curved.The larva is blackish-green, lighter laterally; head and plate of 2 lighter: in silken galleries amongst decaying leaves and twigs of birch.
The adults fly from June to October in the temperate parts of its range (such as Belgium and the Netherlands). The caterpillars feed on decaying plants and dry leaves. They have been found in some fairly unusual locations, such as Buteo nests, straw and thatching, and discarded paper.

Rare
Under 5% of wildlife watchers report a Double-Striped Tabby sighting in Beijing on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 349th most-seen of the 401 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.
July and August
In those months about 10% of wildlife watchers report a Double-Striped Tabby in Beijing on a given day, against under 5% in September to June, the lowest months. Those are among Beijing's wettest months, with about 130 mm of rain a month against almost none in January.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Double-Striped Tabby sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
12th of 12
Of the 12 cities where we can rate Double-Striped Tabby sightings, Beijing ranks 12th at under 5%. The best odds are in Liverpool (United Kingdom, about 10%), Kyiv (Ukraine, under 5%) and Porto (Portugal, under 5%).
GBIF citizen-science records
It is estimated from how often the Double-Striped Tabby is recorded against all the insects logged in Beijing (5 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.
