About the Southern Grizzled Skipper
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.
