Polysarcus denticauda - Bull Bush-cricket
(Charpentier, 1825)

Description: Large, robust species (24-44 mm), with dark green colour. The antennae are shorter than the body. The pronotum is relatively long and saddle-shaped. The wings are only visible as yellowish or brownish scales. The male subgenital plate is bent upwards between the cerci. The ovipositor (18-27 mm) is curved.
Similar species: none
Adults: from June to July
The very loud song consists of three sections and lasts about half a minute. The first and last sections consist of a loud rattle. The middle section is a much faster, high-pitched buzz, which is interrupted for a brief moment by a single high-pitched, loud sound. Males often climb to the top of taller plants and grasses to sing.
