Siona lineata, the black-veined moth, is a moth of the family Geometridae. The species was first described by Giovanni Antonio Scopoli in his 1763 Entomologia Carniolica. Siona lineata oenotriensis (Staudinger, 1915). This rather common species can be found throughout Europe. It is quite rare in the United Kingdom, only being found in east Kent. It is also present in the Amur and Ussuri Regions, southern Siberia, central Asia, Kazakhstan, Caucasus, Asia Minor and Russia.
These moths inhabit limestone and chalk grassland, rough downland, open woodlands, pastures and grassy areas. The wingspan is 35–40 mm. Wings are white or cream coloured with dusky veins in the upperside and black or dark brown veins on the underside. The underside of the wings usually shows also a blackish transverse stripe beyond the middle, very faint in the hindwings.

Rare
Under 5% of wildlife watchers report a Black-Veined Moth sighting in Vienna on a given day, based on 33 verified sightings from GBIF citizen-science data. It is the 431st most-seen of the 1406 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
In that month about 10% of wildlife watchers report a Black-Veined Moth in Vienna on a given day, against under 5% in June to April, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Black-Veined Moth sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 13
Of the 13 cities where we can rate Black-Veined Moth sightings, Vienna ranks 8th at under 5%. The best odds are in Kharkiv (Ukraine, about 10%), Prague (Czechia, about 10%) and Novosibirsk (Russia, about 10%).
Same family: Geometridae
The closest relatives of the Black-Veined Moth that you can see in Vienna (family Geometridae, Geometer Moths) are Mottled Umber (about 20%), Small Dusty Wave (about 10%) and Willow Beauty (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-Veined Moth is recorded against all the insects logged in Vienna (33 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.
