Cerura vinula, the puss moth (pronounced, puuss), is a lepidopteran from the family Notodontidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. The head, thorax, and body of these moths are very fluffy, with a cat-like appearance (hence the common English name puss moth). The antennæ are bipectinated. They have white or yellowish-gray forewings crossed by several wave-like dark lines. The hindwings are light gray or whitish in the males, while in the females they are suffused with blackish but almost transparent. The body is whitish gray, with the dorsal abdomen banded in black.
The caterpillars grow to about 80 millimetres (3.1 in) long. They are at first completely black and moult to light green with a dark dorsal pattern outlined in white... Wikipedia →

Rare
Under 5% of wildlife watchers report a Puss Moth sighting in Moscow on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 677th most-seen of the 1111 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Puss Moth in Moscow on a given day, so our monthly data shows no clear season.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Puss Moth sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 4 cities where we can rate Puss Moth sightings, Moscow ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Birmingham (United Kingdom, under 5%), Saint Petersburg (Russia, under 5%) and London (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Puss Moth is recorded against all the insects logged in Moscow (10 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.
