Poecilimon hamatus Brunner von Wattenwyl, 1878 ♂
Güzelçamlı, AYDIN ● Turkey
With thanks to Luc Willemse for the ID.
Taxonomy:The genus Poecilimon, with more than 150 species, is the largest genus of the family Phaneropteridae. According to DNA data (Ullrich et al. 2010) the most basal branch of the genus is formed by the P. hamatus group (Hamatopoecilimon n. subgen.). The species included in this group are: P. hamatus, P. paros, P. klausgerhardi, P. deplanatus, P. ikariensis and P. unispinosus.
Description: 16-18 mm length. Antennae black.
Biology: Like all tettigonioids, Phaneropteridae communicate acoustically to find a mate. But unlike most other bush-crickets, where the mute female approaches the singing male, in Phaneropteridae typically the female responds acoustically to male song. This may be one of the reasons why some phaneropterid species have very complicated song patterns (e.g. Walker et al., 2003).
The coloration and a male calling song composed of series of short syllables, which follow each other at a relatively high frequency (9–26 Hz at 25°C), are important characteristics of the group P. hamatus. The females respond acoustically to the male song with a delay of about 30 ms.
Distribution: Western Turkey (incl. Izmir region), Greek island of Rhodes.
