Zygaena purpuralis, the transparent burnet, is a moth of the family Zygaenidae. Zygaena purpuralis is a medium-sized moth with a wingspan reaching 30–34 millimetres (1.2–1.3 in). Usually the forewings show three bright red longitudinal streaks quite variable in shape, with almost transparent greyish-bluish edges. Hindwings are more extensively or almost completely bright red. Head and thorax are black, while the abdomen is dark blue. Larvae are yellow, with some lines of small black spots.
Z. purpuralis Brunnich (= pilosellae Esp.; minos Fuessl.). In this species the hindmargin of the forewing (base included) is all black, while the red wedge-spots situated before it may be shaped entirely as in erythrus Hbn. An aberration with light yellow instead of red markings, already recorded by Ochsenheimer, has more lately been named by Ruhl ab. grossmanni (= lutescens Tutt). It is said to have been observed as a constant or at least prevalent form in certain very limited localities. In ab. obscura Tutt the entire wings, inclusive of the red colour, is darkened. — sareptensis Stgr.-Reb. [ now Zygaena minos ssp. sareptensis... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Transparent Burnet is recorded against all the insects logged in Pyrénées National Park (43 verified sightings from 2019 to 2026), 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.
