Summary
Phaneroptera nana, the Mediterranean katydid or southern sickle bush-cricket, is a species known for its distinct appearance and ecological impact as an invasive herbivore in various regions, particularly in the United States after being introduced from Europe.
Physical Characteristics
Adult males grow 13–15 mm long, females 15–18 mm. Basic coloration light green with many small black spots; bright orange eyes; possible brown dorsal stripe on forewings. Hindwings longer than tegmina, which are approximately three-fourths the length of hindwings. In males, cerci are prominent and curved; females have a 5 mm sickle-shaped ovipositor.
Identification Tips
Males have a tapering subgenital plate, while P. falcata has a divergent plate with lobes. Protonum of P. nana is narrower than tall, whereas P. falcata's protonum is about equal in width and length.
Habitat
Sunny and dry habitats, especially shrubs and low branches of trees.
Distribution
Native to mainland Europe, Near East, and North Africa. Introduced to U.S. with records in San Francisco Bay Area, Los Angeles Basin, Portland (Oregon), and parts of the Northeast U.S. (New York, New Jersey, Pennsylvania, Massachusetts).
Diet
Feeds on immature pears in orchards and has been recorded consuming pupae of L. botrana.
Life Cycle
Eggs are laid in the plant lamina, hatching typically occurs in summer, allowing for observation during summer and fall.
Reproduction
Females sing in response to males' chirps to attract them; they are selective and prefer longer chirps. Interaction necessitates a response within 60 milliseconds from the female. Oviposition involves bending the abdomen to create an opening in the plant lamina.
Ecosystem Role
As an invasive herbivore, it can impact agricultural systems, particularly pear orchards.
Economic Impact
Known to damage pear crops.
