Fig. 5. Reproductive states of acoustically communicating grasshopper females between imaginal moult and first oviposition. Upper part summarises a scheme that was
proposed by Loher and Huber (1964) based on experimental data from studies on Gomphocerus rufus and Euthystira brachyptera. Details are explained in the text body to Fig. 1.
In contrast to this scheme, Ch. biguttulus females do not assume a state of ‘passive copulatory readiness’, re-establish ‘active copulatory readiness’ after matings and may
copulate multiple times before their first oviposition.
