...-history, physiological and behavioral traits. We used the variable field cricket, Gryllus lineaticeps , which exhibits a wing dimorphism that mediates two distinct life-history strategies during early adulthood. Long-winged individuals invest in flight musculature and are typically flight capable, whereas...

We studied this question, using crickets, which respond to a short air-puff by oriented walking activity mediated by...

...Kelly M. Seagraves; Berthold Hedwig The cricket's auditory system is a highly directional pressure difference receiver whose function is hypothesised to depend on phase relationships between the sound waves propagating through the auditory trachea that connects the left and right hearing organs. We...

Ormia females home in on the male cricket's songs and deposit larvae, which burrow into the cricket, feed and emerge to pupate. Because male crickets call at night, gravid female Ormia in search of hosts are subject to...
