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.
Seitz- The specimens of the first brood larger, predominantly grey-brown, those of the second brood smaller, light straw-colour. 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 →

Rare
Under 5% of wildlife watchers report a Pale Prominent sighting in Vienna on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 838th most-seen of the 1406 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 Pale Prominent in Vienna on a given day, so our monthly data shows no clear season.
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.
11th of 12
Of the 12 cities where we can rate Pale Prominent sightings, Vienna ranks 11th at under 5%. The best odds are in Liverpool (United Kingdom, about 10%), Porto (Portugal, about 10%) and Manchester (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Pale Prominent is recorded against all the insects logged in Vienna (11 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.
