“…The percentages of marked individuals seen again are comparable with those recorded in other studies on Orthoptera (Heller & von Helversen, 1990;Kindvall et al, 1998;Diekötter et al, 2005Diekötter et al, , 2007. Marking with reflective material has resulted in day-to-day percentages of individuals seen again of more than 80% (Hein et al, 2003;Heidinger et al, 2009).…”

“…A more or less steady decrease in the percentage seen again over time (Hein et al, 2003;Diekötter et al, 2007) due to mortality and emigration (Heller & von Helversen, 1990;Narisu et al, 1999) is typical. The loss of the marks, which is common when reflective material is fixed to the femur (Heller & von Helversen, 1990;Hein et al, 2003), was not observed during this study and is thus unlikely to have affected the results.…”

“…All of them were marked with reflective material (3M Scotchlite 7610 high gain) so that they could be located at night by using a headlamp (Heller & von Helversen, 1990). Marking was done by gluing small pieces (2.5 mm in diameter) of reflective tape on the paranota (Kindvall, 1999; Fig.…”

“…1). This modified marking technique was used because bush-crickets that were marked by fixing the reflective tape around the hind femur (Heller & von Helversen, 1990) tried to bite off their hind legs. In addition, individuals of M. roeselii were marked individually with honey-bee markers on the dorsum of the pronotum (Ingrisch & Köhler, 1998;Kindvall, 1999;Fig.…”

Does wing dimorphism affect mobility in Metrioptera roeselii (Orthoptera: Tettigoniidae)?

Abstract. Range shifts are among the most conspicuous effects of global warming. Marked changes in distribution are recorded both for highly mobile species of insects, which are capable of flight, and wing-dimorphic species with predominantly short-winged individuals. One of these species is the bush-cricket Metrioptera roeselii, which occasionally produces long-winged individuals. However, there is little known about the locomotory behaviour of wing-dimorphic insects. Yet to be able to predict potential range shifts it is necessary to know the dispersal potential of macropters. Therefore, an experiment was conducted in which individually marked M. roeselii were released at four sites. Different movement parameters, such as daily movement, activity radius, dispersal range, net displacement and crowding rate, were calculated. The statistical analyses showed that the movement of long-winged and shortwinged individuals did not differ, but the percentage of individuals that were not seen again was twice as high for long-winged bushcrickets. These results suggest that most of the long-winged individuals that were seen again did not fly; i.e., they had the same basic mobility as the short-winged individuals. However, the comparatively low number of long-winged individuals that were seen again suggests that at least some macropters are long-distance dispersers, which is relevant for the dispersal process. The comparison of sexes showed that males were significantly more mobile than females. This sex-specific locomotory behaviour in M. roeselii might depend on a complex series of social interactions and physiological conditions.

“…Duration of spermatophore consumption. On 27 May 1990, 120 females were marked individually with reflective tape and adheasive labels (for details of method see Heller and Helversen 1990) and released at the place of capture. During two arbitrarily choosen days (28 May and 5 June) we searched for the marked animals every 1-2 h and examined them for the presence of spermatophores.…”

The ultimate function of nuptial feeding in the bushcricket Poecilimon veluchianus (Orthoptera : Tettigoniidae : Phaneropterinae)

Summary. During mating the males of the bushcricketPoecilimon veluchianus transfer a large spermatophore of about a quarter of their body weight to the female. Such nuptial feeding is often thought to function as paternal investment by increasing the fitness of the male's offspring. According to an alternative, though not mutually exclusive, hypothesis, the size of the spermatophore is maintained because of its function as a sperm protection device. In this case the cost to the male should be classified as mating effort. To discriminate between these two hypotheses we measured the duration of sperm transfer into the female spermatheca and the time taken for spermatophore consumption. A comparison of durations revealed that spermatophore consumption interferes with the process of sperm transfer (Fig. 4). There was no significant effect of spermatophore consumption on number of eggs laid, weight of eggs or absolute weight of hatched larvae. The relative dry weight of hatched larvae, however, was increased as a result of spermatophore consumption (Table 1). Thus spermatophylax size is adjusted in accordance with a sperm protection function and the spermatophylax therefore represents mating effort. The increase in relative dry weight indicates that there may also be a paternal investment effect of the spermatophylax, if the offspring that benefit from spermatophylax materials are fathered by the donating male.
