Genus Scapteriscus
two-clawed mole crickets

Timing of flight and calling for S. vicinus (above) and S. borellii (below). Dark bars indicate when males of each species call. Unshaded curves show the distribution of take-off times; shaded curves show the distribution of landing times. Both species fly and call for little more than an hour beginning shortly after sunset, with tawny mole crickets preceding southern mole crickets by 5 to 15 minutes.
