Phaneroptera nana, common name southern sickle bush-cricket, is a species in the family Tettigoniidae and subfamily Phaneropterinae. It has become an invasive species in California where it may be called the Mediterranean katydid.
This bush cricket is native to mainland Europe, the Near East and North Africa. The Indo-Malayan species Phaneropera subcarinata, described by Bolívar, is morphologically similar to P. nana, and was classified under the P. nana name by Carl Brunner von Wattenwyl. As an invasive species, it has spread to the San Francisco Bay Area and may be widespread in the Los Angeles Basin, with records of its presence in California dating from at least 1952. In addition, it has been recorded in Portland, Oregon since 2015 and South America and hypothesized in the Annals of Carnegie Museum to have spread via shipping.
It mainly inhabits sunny and dry habitats, especially shrubs and low branches of trees. The adult males grow up to 13–15 millimetres (0.51–0.59 in) long, while females can reach 15–18 millimetres (0.59–0.71 in) of length. In both sexes, the basic coloration of the body is light green, with many small black... Wikipedia →

With luck
About 10% of wildlife watchers report a Mediterranean Katydid sighting in Fertő-Hanság National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 44th most-seen of the 243 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Mediterranean Katydid in Fertő-Hanság National Park on a given day, against under 5% in October to April, the lowest months. That is one of Fertő-Hanság National Park's wettest months, with about 80 mm of rain against 30 mm in March.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Mediterranean Katydid sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 5
Of the 5 parks where we can rate Mediterranean Katydid sightings, Fertő-Hanság National Park ranks 2nd at about 10%. The best odds are in Kiskunság National Park (Hungary, about 20%).
Same family: Tettigoniidae
The closest relatives of the Mediterranean Katydid that you can see in Fertő-Hanság National Park (family Tettigoniidae, Katydids) are Great Green Bush-Cricket (about 20%), Striped Bush-Cricket (about 20%) and Wart-Biter (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mediterranean Katydid is recorded against all the insects logged in Fertő-Hanság National Park (17 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.
