Catocala coniuncta
In 3 days ~10% in a week ~30%
Catocala coniuncta is a circum-Mediterranean species of moth whose range extends across southern Europe, North Africa and extending to the Middle East. Its species name has for a long time been misspelled "conjuncta"; this was only corrected in 2010.
Like other related species C. coniuncta has mottled brown fore-wings and crimson-red hind-wings with a black central line. The species differs from its European congeners in the shape of the post-median line on the fore-wing and the straighter black line on the hind-wings. The larvae feed on holm oak (Quercus ilex).
Extra-limitally, C. coniuncta has occurred just once in Britain, being found at light by Robin Harvey at the RSPB Minsmere reserve on the Suffolk coast on 14 September 2004. Following this record the English name Minsmere crimson underwing has been adopted. Wikipedia →

Rare
Under 5% of wildlife watchers report a Minsmere Crimson Underwing sighting in Madrid on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 274th most-seen of the 457 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Minsmere Crimson Underwing in Madrid on a given day, against under 5% in August to June, the lowest months. That is one of Madrid's driest months, with about 10 mm of rain against 65 mm in October.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Minsmere Crimson Underwing sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
2nd of 2
Of the 2 cities where we can rate Minsmere Crimson Underwing sightings, Madrid ranks 2nd at under 5%. The best odds are in Porto (Portugal, about 10%).
GBIF citizen-science records
It is estimated from how often the Minsmere Crimson Underwing is recorded against all the insects logged in Madrid (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.
