Pholidoptera griseoaptera, the dark bush-cricket, is a flightless species of European bush-cricket; it is the type species of its genus with no subspecies. Pholidoptera griseoaptera can reach a body length of 11 to 21 mm (males) and 15 to 20 mm (females), much smaller than the similar Pholidoptera aptera. The sickle-shaped and upward curved ovipositor of the females is 8 to 10 mm long, while the males have two short cerci. The antennae and the hind legs are quite long.
The rounded brachypterous wings of the males are brown with light brown to ochre-coloured edges and are about 5 mm in length (about as long as the pronotum). The females are almost wingless or have half-round, grey-brown fore-wings that are 1–2 mm long. Long-winged (macropterous) forms are not recorded.
This species can be found in Europe from northern Spain up to Crimea, Caucasus and the Near East. It is fairly common in Great Britain, but not recorded from Ireland. On the Isle of Man the species is legally protected under Schedule 5 of the Wildlife Act 1990, being found at only two coastal sites (Lonan and Glen Maye) at the extreme north of the species’ British Isles...

GBIF citizen-science records
It is estimated from how often the Dark Bush-Cricket is recorded against all the insects logged in Picos de Europa National Park (7 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.
