Eupoecilia ambiguella
In 3 days ~20% in a week ~30%
Eupoecilia ambiguella, the vine moth or European grape berry moth, is a Palearctic moth species of the family Tortricidae. It was first described in 1796 (as Tinea ambiguella) by Jacob Hübner. It is an economically significant grape pest species.
Most sources state the wingspan as 12–15 mm, although Zhang and Houhun instead give it as 9–15 mm. The distribution range of Eupoecilia ambiguella stretches from the United Kingdom to Japan, occurring north up into Fennoscandia and south to the Mediterranean Basin. Its range overlaps in part with that of Lobesia botrana, but E. ambiguella prefers colder, more humid environments than L. botrana, and in shared areas may be found at a higher altitude or co-occurring in the same vineyard.
The larvae are polyphagous, with more than thirty known host plants including dogwood, smooth bedstraw, blackthorn, Virginia creeper, grape and honeysuckle. According to some sources, its original host plant is common mugworth (Artemisia vulgaris), but according to Ioriatti, Lucchi and Varela, "grapevine is now accepted as its original host."

With luck
About 10% of wildlife watchers report a Vine Moth sighting in Bavarian Forest National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 661st most-seen of the 1115 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.
April–May and July–August
In those months about 10% of wildlife watchers report a Vine Moth in Bavarian Forest National Park on a given day, against under 5% in June and September–March, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Vine Moth sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Bavarian Forest National Park, in our data
Bavarian Forest National Park is the only park on Wallace's Line with enough records to rate Vine Moth sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Tortricidae
The closest relatives of the Vine Moth that you can see in Bavarian Forest National Park (family Tortricidae, Tortricid Leafroller Moths) are Common Marble (about 10%), Arched Marble (about 10%) and Barred Fruit-Tree Tortrix (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Vine Moth is recorded against all the insects logged in Bavarian Forest National Park (9 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.
