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...

Possible
About 20% of wildlife watchers report a Dark Bush-Cricket sighting in Bavarian Forest National Park on a given day, based on 80 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 34th most-seen of the 1115 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
August
In that month about 30% of wildlife watchers report a Dark Bush-Cricket in Bavarian Forest National Park on a given day, against under 5% in December to March, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Dark Bush-Cricket sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 10
Of the 10 parks where we can rate Dark Bush-Cricket sightings, Bavarian Forest National Park ranks 2nd at about 20%. The best odds are in Triglav National Park (Slovenia, about 30%).

GBIF citizen-science records
It is estimated from how often the Dark Bush-Cricket is recorded against all the insects logged in Bavarian Forest National Park (80 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.
