Pterostoma palpina, the pale prominent, is a moth from the family Notodontidae. The species was first described by Carl Alexander Clerck in 1759.

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.

With luck
About 10% of wildlife watchers report a Pale Prominent sighting in Wadden Sea National Park on a given day, based on 29 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 214th most-seen of the 818 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Pale Prominent is recorded against all the insects logged in Wadden Sea National Park (29 verified sightings from 2019 to 2026), 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.
