Yersinella raymondii, also known as Raymond's bush-cricket, is a species of "katydids crickets" belonging to the family Tettigoniidae subfamily Tettigoniinae. The scientific name Yersinella comes from the name of the entomologist who has described the species in 1860.
This quite common cricket is mainly present in Albania, Austria, Bosnia and Herzegovina, Croatia, France, Hungary, Romania, Italy, Greece, Serbia, Slovakia, Slovenia, Spain and Switzerland. These "katydids crickets" mainly inhabit forest edges, open forests and Mediterranean shrubland, at an elevation up to 1,600 metres (5,250 ft) above sea level. They prefer shrubs and low herbaceous plants or soil, rather than tall grasses. As a matter of fact they live in hilly and mountainous areas, in the margins of forests and woodlands, as well in open areas with plenty of vegetation.
Yersinella raymondii is rather small species, the adults grow up to about 12–16 millimetres (0.47–0.63 in) long, while females reach a maximum of 25–26 millimetres (0.98–1.02 in), including the relatively conspicuous, slightly and evenly bent upwards ovipositor (about 8–11 millimetres (0.31–0.43 in...

With luck
About 10% of wildlife watchers report a Raymond's Bush-Cricket sighting in Milan on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 145th most-seen of the 351 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.
June to October
In those months about 10% of wildlife watchers report a Raymond's Bush-Cricket in Milan on a given day, against under 5% in November to May, the lowest months.

GBIF citizen-science records
It is estimated from how often the Raymond's Bush-Cricket is recorded against all the insects logged in Milan (17 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.
