Macrothylacia rubi, the fox moth, is a lepidopteran belonging to the family Lasiocampidae. It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. This species can be found from Western Europe to Central Asia and Siberia. These moths live in open woodlands, moors and prairies.
The wingspan of the male is 40–65 mm. The wings are reddish brown in males while females are usually paler, more greyish in colour and slightly larger than males. Both sexes show two narrow, straight, light-yellow, transverse bands, running across the forewings. The abdomen is thick, grey brown and hairy. The caterpillars can reach a length of about 80 millimetres (3.1 in). They are initially black with bright yellow or orange segments, later they become darker, always covered with blackish and tawny-coloured hairs and with light grey hair on the sides.
It is a univoltine species. Between September and March the caterpillars hibernate in leaf litter. These moths take flight from May to July. The males usually fly in the afternoon and night, while the females fly only at night. Caterpillars feed on heather (Calluna) bramble... Wikipedia →

Possible
About 20% of wildlife watchers report a Fox Moth sighting in Białowieża National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 62nd most-seen of the 158 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September
In that month about 30% of wildlife watchers report a Fox Moth in Białowieża National Park on a given day, against under 5% in April–May and October–February, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Fox Moth sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
14th of 19
Of the 19 parks where we can rate Fox Moth sightings, Białowieża National Park ranks 14th at about 20%. The best odds are in Hortobágy National Park (Hungary, about 30%), Biebrza National Park (Poland, about 30%) and Snowdonia National Park (United Kingdom, about 30%).
GBIF citizen-science records
It is estimated from how often the Fox Moth is recorded against all the insects logged in Białowieża National Park (10 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.
