Ancylis obtusana, the small buckthorn roller, is a moth of the family Tortricidae. This species is present in most of Europe, in the eastern Palearctic realm, and in the Near East. These moths inhabit marginal areas of forests where host plants grow.
Ancylis obtusana has a wingspan of about 12 millimetres (0.47 in). The forewings are red brown, with a rounded reddish patch and the costa stringulated (finely streaked) with white and brown. The hind wings are brownish. Meyrick describes it - Forewings ferruginous, costa with dark fuscous and whitish strigidae; basal patch dark ferruginous-brown except towards costa, edge rounded,
very oblique, reaching beyond middle of dorsum, followed by a grey-whitish stria broadly enlarged on costa; central fascia dark ferruginous-brown, with strong posterior median projection, not reaching dorsum; costal area beyond this dark ferruginous; ocellus small, broadly edged with leaden- metallic. Hind wings fuscous, darker terminally. Julius von Kennel provides a full description.
Similar species are Ancylis comptana and Ancylis mitterbacheriana. The adult moths fly from May to July. Larvae feed... Wikipedia →

Rare
Under 5% of wildlife watchers report a Small Buckthorn Roller sighting in Bavarian Forest National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 964th most-seen of the 1115 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 and June
In those months about 10% of wildlife watchers report a Small Buckthorn Roller in Bavarian Forest National Park on a given day, against under 5% in July to April, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Small Buckthorn Roller sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen 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 Small Buckthorn Roller sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Ancylis
The closest relatives of the Small Buckthorn Roller that you can see in Bavarian Forest National Park (genus Ancylis) are Aspen Roller (about 10%), Buckthorn Roller (about 10%) and Red Roller (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Small Buckthorn Roller is recorded against all the insects logged in Bavarian Forest National Park (5 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.
