Pterostoma palpina, the pale prominent, is a moth from the family Notodontidae. The species was first described by Carl Alexander Clerck in 1759. The moth can be found in Europe and Central Asia (Palearctic realm). Pterostoma palpina has a wingspan of 35 to 52 mm. Beyond the black scaled tooth-like forewing projection the inner margin is notched. Long labial palps and tufts on the tail segment, give an elongated appearance. The antennae of the female are pectinated, but the teeth are shorter than those of the male; and the blackish streak on the wings are usually less defined. Except that some specimens are more strongly marked than others there is little variation. The larva is bluish green, with white dorsal and lateral lines, and a black edged yellow stripe along the spiracles; this stripe is marked with reddish on the three anterior segments.

The transverse bands of the forewing only indicated by black vein-dots, the postdiscal band more complete than the other, being marked by double dots separated by white and placed... Wikipedia →

With luck
About 10% of wildlife watchers report a Pale Prominent sighting in Manchester on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 278th most-seen of the 458 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
May and July–September
In those months about 10% of wildlife watchers report a Pale Prominent in Manchester on a given day, against under 5% in June and October–April, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Pale Prominent 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.

GBIF citizen-science records
It is estimated from how often the Pale Prominent is recorded against all the insects logged in Manchester (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.
