The mouse moth (Amphipyra tragopoginis) is a moth of the family Noctuidae. It is a widespread species with a Holarctic distribution. Europe (except the extreme north, and not occurring in the south of Spain, Sicily, or the Balkans); also in Armenia, Asia Minor, Syria, Iran, Western Siberia, Kashmir (extending thence into Punjab). Recently introduced in Canada and North America.
This is a rather drab but distinctive species. The forewings are uniform dark brown with three blackish spots arranged in a triangle. The hindwings are buffish, darker towards the margins. The wingspan is 32–40 mm. The common name derives from the species' habit of scuttling away on foot when disturbed rather than flying. Despite this, it can fly strongly and is attracted to light, sugar and nectar-rich flowers. In the British Isles, the adult is active from July to September.
Forewing dull brown, dusted with paler scales, varying from pale to blackish brown; submarginal line only visible, indicated by a paler tinge preceded by a darker shade; orbicular stigma a blackish dot; reniform represented by two, one above the other, at end of cell; hindwing rufous fuscous, paler...

Rare
Under 5% of wildlife watchers report a Mouse Moth sighting in Wadden Sea National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 699th most-seen of the 818 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report a Mouse Moth in Wadden Sea National Park on a given day, against under 5% in September to July, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Mouse Moth sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Mouse Moth sightings, Wadden Sea National Park ranks 2nd at under 5%. The best odds are in Gros Morne National Park (Canada, about 10%).
GBIF citizen-science records
It is estimated from how often the Mouse Moth is recorded against all the insects logged in Wadden Sea 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.
