@article {58247, title = {Role-reversal in katydids: Habitat influences reproductive behaviour (Orthoptera: Tettigoniidae, Metaballus sp.)}, year = {1985}, abstract = {

Mating behaviour of the katydid Metaballus sp. varies. At sites QS and DB (in 1982) females competed for access to calling males and males chose mates by mating with heavier, more fecund females. At another site (BR) there was no evidence of role-reversal in reproductive behaviour, and males were observed to compete for mates. This species has a large spermatophore, a product of male reproductive glands, that is eaten by the female after mating. Males at the DB site had small reproductive glands. This suggests that some aspect of the QS and DB environments decreases spermatophore production; spermatophores become a limiting resource for females resulting in the reversal in reproductive roles observed at these sites. A field experiment that involved moving individuals from site BR to QS in 1983 determined that mating system was influerced by site (Table 1). At BR, males produced a continuous calling song, a third of the males observed attracted mates, and called for about 30 min before the female arrived; courtship duration was short. Males that were moved from BR to QS encountered a higher density of receptive females as all males attracted females after an average of just 3 min of calling. They changed their behaviour by producing short periodic bursts of song (\“zipping\”), and by courting females for long periods of time. The long courtship period may function as as a mate-assessment period for males. The reproductive behaviour of BR males moved to QS differed from that of native QS males only in the length of time spent in copula.

We have investigated the effects of alterations of several temporal parameters of auditory stimuli, as well as of stimulus intensity changes, on the attractiveness of these stimuli to femaleTeleogryllus oceanicus, as measured by monitoring sound-elicited flight steering responses. AlthoughT. oceanicus has a rhythmically complex calling song, females are attracted by a simpler model consisting of regularly repeating sound pulses. We have found that the two major temporal features of this model, sound pulse duration and pulse repetition rate, are both important for eliciting phonotactic steering responses.

Stimuli with altered temporal features had intensity thresholds indistinguishable from the control stimulus (Fig. 3). The majority of crickets, however, ceased to respond to the altered stimuli when the stimulus intensity was sufficiently increased (Figs. 4\–7). In some cases, intensity increases resulted in a reversal of the steering response from positive to negative (Fig. 10). Effects of altered temporal parameters were also apparent at lower stimulus intensities, where the amplitudes of steering responses to stimuli with altered parameters were smaller than those in response to the control stimulus (Figs. 8, 9).

We considered the possibility that the cessation of responsiveness to stimuli with altered temporal features was due to a temporal pattern-specific diminution of binaural cues for sound localization at high intensities. Experiments performed with unilaterally deafened crickets (Fig. 11) led us to conclude that this was not the case, and that our findings instead reflect the properties of the song recognition mechanism.

Experiments were conducted on Mygalopsis marki Bailey to determine the response of calling males to singing intruders. By increasing the density of natural aggregations of singing males we were able to observe the behavioural responses of individuals. In high density situations, males sang from lower perches in their plant and this effect was correlated with each male\&$\#$39;s proximity to other calling males. Furthermore, to examine if resident males were affected by conspecific song, a playback technique was employed using tape recordings of M. marki song. The design of the experiment was such that when confronted with an intruder, steadily increasing the intensity of its song, resident males moved to a lower position in the plant and ceased singing.

Males and females of the oedipodine grasshopper Sphingonotus rubescens crepitate by producing a click-buzz sound. Males have 3 types of stridulation: (1 and 2) a common whistkle-click combination lasting less than 1 sec and often followed by a hop-turn or very short flight, and (3) a bussing lasting ca. 1.2 sec when 2 or more males are less than 1m apart. Male courtship behviour is described.
