The silver Y (Autographa gamma) is a migratory moth of the family Noctuidae which is named for the silvery Y-shaped mark on each of its forewings. The species is widespread throughout most of the palearctic. The silver Y is a medium-sized moth with a wingspan described in the range of 30-45 mm.
The wings are intricately patterned with various shades of brown and grey serving as camouflage. In the centre of each forewing there is a silver-coloured mark shaped like a lower case Y (y) or a lower case Greek letter gamma (γ). There are several different forms with varying colours depending on the climate in which the larvae grow.

With luck
About 10% of wildlife watchers report a Silver Υ sighting in Hohe Tauern National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 93rd most-seen of the 165 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Silver Υ in Hohe Tauern National Park on a given day, against under 5% in February–May and September–October, the lowest months. December has too few records to rate.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Silver Υ sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
11th of 18
Of the 18 parks where we can rate Silver Υ sightings, Hohe Tauern National Park ranks 11th at about 10%. The best odds are in Snowdonia National Park (United Kingdom, about 20%), Kiskunság National Park (Hungary, about 20%) and Wadden Sea National Park (Germany, about 20%).
GBIF citizen-science records
It is estimated from how often the Silver Υ is recorded against all the insects logged in Hohe Tauern National Park (7 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.
