1-11-2019 MONTE CORONA, VALENCIA - MEDITERRANEAN KATYDID (Phaneroptera nana)


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 spots. The eyes are bright orange. In some individuals, there may be a brown dorsal stripe where the forewings (tegmina) meet, though the stripe does not extend onto the pronotum. The hindwings are longer than the tegmina, with the tegmina approximately three-fourths of the length of the hindwings. In some specimens, the tegmina reach the apex of the posterior femurs. In adult males, the cerci are prominent and curved, while in adult females, the ovipositor is about 5 millimetres (0.20 in) long and has the shape of a sickle.
