Pyrgus malvoides, the southern grizzled skipper, is a species of skipper (family Hesperiidae). The wingspan of this butterfly is 24–26 mm. Pyrgus malvoides cannot be distinguished from Pyrgus malvae by external characteristics, but this is quite possible on the basis of the genital structures (H. malvoides Elw. Markings as in malvae; tergite of anal segment (male) with a tooth on each side).
From the other species of the genus Pyrgus, both species can be clearly differentiated by the presence of the mostly clear submarginal points on the upper side of the wing. Pyrgus malvoides is distributed from Portugal and Spain via southern and central France, southern Switzerland (south of the main Alpine ridge) and Austria (Vorarlberg, Tyrol) to Italy and Istria.
According to previous knowledge, Pyrgus malvoides colonizes various fresh and above all moist habitats in the Alps if these have structures that are favorable to the microclimate, such as open ground on gravel, rocks, obstructions from cattle kicking or erosion, etc. A syntopic occurrence with Pyrgus malvae could not be determined so far.

Rare
Under 5% of wildlife watchers report a Southern Grizzled Skipper sighting in Milan on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 221st most-seen of the 351 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May to August
In those months about 10% of wildlife watchers report a Southern Grizzled Skipper in Milan on a given day, against under 5% in September to April, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Southern Grizzled Skipper sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Milan, in our data
Milan is the only city on Wallace's Line with enough records to rate Southern Grizzled Skipper sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Hesperiidae
The closest relatives of the Southern Grizzled Skipper that you can see in Milan (family Hesperiidae, Skippers) are Far Eastern Large Skipper (about 10%) and Mallow Skipper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Southern Grizzled Skipper is recorded against all the insects logged in Milan (9 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.
