Modicogryllus Modicogryllus frontalis

Modicogryllus frontalis (Fieber, 1845) (Figs. 4; 11; 18) - males can be heared stridulating from early July until late September. The echemes are composed of 18-20 hemisyllables and the gaps between those echemes are variable between 0.1 and 3 seconds, depending on the temperature. For example, at 29oC those gaps are 0.2-1.5 seconds. The echeme has 0.2-0.3 seconds. Modicogryllus frontalis begins its stridulation in the afternoon and at night, but not rarely we can hear this species singing at day time (especially in sunny days). Pars stridens is approximately 1,2 mm long (area with stridulatory pegs) and has 139 pegs. [1]
