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 →

Rare
Under 5% of wildlife watchers report a Mediterranean Katydid sighting in San Diego on a given day, based on 107 verified sightings from GBIF citizen-science data. It is the 96th most-seen of the 693 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.
May to October
In those months about 10% of wildlife watchers report a Mediterranean Katydid in San Diego on a given day, against under 5% in November to April, the lowest months. Those are among San Diego's driest months, with about 10 mm of rain a month against 55 mm in February.
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.
27th of 29
Of the 29 cities where we can rate Mediterranean Katydid sightings, San Diego ranks 27th at under 5%. The best odds are in Portland (United States, about 20%), Vienna (Austria, about 20%) and Lyon (France, about 20%).
GBIF citizen-science records
It is estimated from how often the Mediterranean Katydid is recorded against all the insects logged in San Diego (107 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.
