Cyclophora annularia
In 3 days ~10% in a week ~20%
Cyclophora annularia, the mocha, is a moth of the family Geometridae. The species was first described by Johan Christian Fabricius in 1775 and it can be found in Europe. Its wingspan is 18 to 22 millimetres (0.71 to 0.87 in). Normally, the wings of this species are yellowish white, inclining to ochreous yellow with the blackish central shade near to and sometimes united with the blackish irregular and outwardly toothed second cross line on both fore and hind wings. The rings are deep brown or blackish. There is variation in the width and intensity of the central shade, and the rings sometimes are absent on the fore wings (ab. obsoleta, Riding), and occasionally all the wings are devoid of the annular mark (ab. biobsoleta, Riding). Examples of a second generation reared in captivity are rather deeper coloured, and have a sprinkling of black scales, chiefly on the fore wings.
The caterpillar is dark green, yellow between the rings; there are three yellow lines along the back, the outer ones waved. The head is reddish brown, paler marked. There is also a pale ochreous brown form. Adults are on wing from May to August depending on the location. The larvae feed on maple tree leaves.
The name derives from a fancied resemblance to the Mocha stone. Wikipedia →

Rare
Under 5% of wildlife watchers report a The Mocha sighting in Prague on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 505th most-seen of the 724 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.
April
In that month about 10% of wildlife watchers report a The Mocha in Prague on a given day, against under 5% in May to March, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most The Mocha sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
4th of 6
Of the 6 cities where we can rate The Mocha sightings, Prague ranks 4th at under 5%. The best odds are in Kharkiv (Ukraine, about 20%), Kyiv (Ukraine, under 5%) and Vienna (Austria, under 5%).
GBIF citizen-science records
It is estimated from how often the The Mocha is recorded against all the insects logged in Prague (8 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.
