The small dusty wave (Idaea seriata) is a moth of the family Geometridae first described by Franz von Paula Schrank in 1802. It is found throughout Western, Central and Northern Europe. In the north, its range extends as far as Denmark and southern Scandinavia. In the east its range extends as far as Russia (Moscow or Veliky Novgorod). Idaea seriata is replaced by the subspecies Idaea seriata canteneraria, from the north-east of Spain and the central and eastern Mediterranean (including the islands, except Crete) to the Crimean peninsula, while the western Mediterranean and the Balearic Islands are inhabited by the sister species Idaea minuscularia. Outside Europe it is found in eastern Algeria, Tunisia, Turkey, Cyprus, the Caucasus and the northwest of Transcaucasia. In Morocco and western Algeria, it is replaced by the sister species Idaea minuscularia. In the British Isles it is common in England and Wales but is only found in the eastern half of Scotland and it is rare in Ireland.
The species is very small (wingspan 19–21 mm) and is probably one of the least striking members of the whole family, being basically grey with all markings indistinct apart from the black discal spot typical of the genus. Wikipedia →

With luck
About 10% of wildlife watchers report a Small Dusty Wave sighting in Athens on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 198th most-seen of the 242 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Small Dusty Wave is recorded against all the insects logged in Athens (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.
