Oecanthus pellucens

Behaviour: 

Oecanthus pellucens (Scopoli, 1763) (Figs. 7; 14; 21) - this species calling song is very common and well known because it can be heard everywhere with exception of the mountains. The species stridulates at night and very rarely we can hear it singing during day time, usually in late autumn. Each echeme has a number of 25-40 hemisyllables and a 0.8-1.2 seconds length. Gaps between two successive echemes are 0.4-1 second long. In the warm nights, the gaps have a very small lenght, meanwhile in the colder autumn nights the gaps have a bigger length, sometimes up to more minutes. The pars stridens has approximately 1.5 mm (area with stridulatory pegs) and only 46 pegs. [1]
