Katha depressa, the buff footman, is a moth of the family Erebidae found in Asia and Europe. It was first described by Eugenius Johann Christoph Esper in 1787. The length of the forewings is 15–17 mm. Both wings dark brown grey, with the costa of the forewing and the fringes light bright yellow, especially in the female. The ground colour is often more or less lightened with ochreous, sometimes almost clay-colour (ochreola Hbn.), or nearly whitish (helveola Ochs.) or of an indefinite intermediate shade (luteola Hbn.). In pavescens Butl. from Hokkaido (Island of Yezo), the wings are dirty greyish yellow; the hindwing lighter.
Katha deplana deplana Katha deplana pavescens (Butler, 1877) (Russia: Middle Amur, Primorye, Sakhalin, Kunashir; Korea; Japan) Larvae are a dirty lead-grey colour, bearing a yellow dorsal stripe with dark edges and three raised black transverse spots anteriorly, posteriorly and in the centre, and black markings laterally. The larvae feed on lichen and algae, especially on conifer trees, but also on oak (Quercus species) and heathers (Calluna species). Until June, on lichens on trees. Pupa... Wikipedia →

Possible
About 20% of wildlife watchers report a Buff Footman sighting in Porto on a given day, based on 221 verified sightings from GBIF citizen-science data. It is the 14th most-seen of the 498 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.
August and October
In those months about 30% of wildlife watchers report a Buff Footman in Porto on a given day, against under 5% in December to April, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Buff Footman 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.
Yes
Of the 4 cities where we can rate Buff Footman sightings, Porto has the highest daily chance: about 20%. Next come London (United Kingdom, about 10%) and Liverpool (United Kingdom, under 5%).
Same family: Erebidae
The closest relatives of the Buff Footman that you can see in Porto (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Swan Moth (about 20%), Ruby Tiger Moth (about 20%) and Rosy Footman (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Buff Footman is recorded against all the insects logged in Porto (221 verified sightings), 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.
