Nemobius sylvestris, the wood cricket, is a flightless species of cricket in the family Trigonidiidae. It is native to Western Europe and North Africa but uncommon in Britain. This cricket is a small, dark brown, ground-dwelling, grasshopper-like insect with long, thread-like antennae. It grows to about 1 cm (0.4 in). Neither males nor females have hind wings; in males the fore-wings extend half way along the abdomen, while in females, the fore-wings are reduced to rounded stubs. Females also have a long ovipositor at the tip of the abdomen.
The wood cricket is native to Europe and North Africa. Its range includes Western, Central and Southern Europe, Corsica, Algeria and Morocco. The natural habitat of this species is forest edges and woodland clearings, where it is associated with oak, beech, hazel and holly trees and with bracken. It thrives among the leaf litter in warm, sunny spots. It is uncommon in Britain, with three separate populations in the New Forest, the Isle of Wight and southern Devon. In 2001, following the clearance of coniferous woodland and rhododendron from a site near Offwell in eastern Devon, a new population appeared... Wikipedia →

Rare
Under 5% of wildlife watchers report a Wood Cricket sighting in Vienna on a given day, based on 41 verified sightings from GBIF citizen-science data. It is the 373rd 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 30%, if each day is a fresh chance.
August to October
In those months about 10% of wildlife watchers report a Wood Cricket in Vienna on a given day, against under 5% in November to July, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Wood Cricket sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 8
Of the 8 cities where we can rate Wood Cricket sightings, Vienna ranks 4th at under 5%. The best odds are in Prague (Czechia, about 10%), Paris (France, about 10%) and Porto (Portugal, about 10%).
Same order: Orthoptera
The closest relatives of the Wood Cricket that you can see in Vienna (order Orthoptera, Grasshoppers, Crickets, and Katydids) are Great Green Bush-Cricket (about 30%), Italian Locust (about 20%) and Mediterranean Katydid (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Wood Cricket is recorded against all the insects logged in Vienna (41 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.
