Water contact during courtship of males of Archisepsis diversiformis (Sepsidae).
نویسنده
چکیده
On uncut plants of Dieffenbachia (Araceae) male aggregations of Archisepsis diversiformis (Sepsidae) were observed fighting with each other and courting females. The males were observed repeatedly orienting toward water droplets, moving next to the droplet and leaning against it, alternatively, to the two sides of the body and using the legs from the opposite side to push against it. This movement was repeated up to seven times in one "bathing" event. The occasional "bath" probably helps to dissipate heat from the body surface, thus preventing a rise in body temperature.

Four hypotheses that could explain the elaborate species-specific morphology of the clasping organs on the front legs of male Archisepsis diversiformis flies were tested: direct male–male combat, mechanical fit, male–female conflict of interests, and male stimulation of the female. Experimental modification of the shape of the male clasper and of the female wing base where the male clasped the ...

Female rejections of males are crucial events in sexual selection by female choice and sexually antagonistic coevolution, but there are few detailed studies of the process of rejection. Female struggles when mounted by males are often assumed to function to dislodge the male. But this study, in which female receptivity was manipulated by using females of different ages, showed that this “dislod...
متن کاملTo paddle or not: context dependent courtship display by male blue crabs, Callinectes sapidus.
The nature of the courtship signalling used by a species is shaped by many factors, one of which is its habitat. Male blue crabs, Callinectes sapidus, have a courtship display in which they elevate their body by standing high on their legs, open their chelae and paddle their swimming legs. This courtship display is not reported in other swimming (portunid) crabs and is rarely expressed in labor...

Internal fertilization without copulation or prolonged physical contact is a rare reproductive mode among vertebrates. In many newts (Salamandridae), the male deposits a spermatophore on the substrate in the water, which the female subsequently takes up with her cloaca. Because such an insemination requires intense coordination of both sexes, male newts have evolved a courtship display, essenti...

Several possible explanations for the elaborate species-specific morphology of male front leg clasping organs were tested by comparing six species of Archisepsis, Palaeosepsis and Microsepsis flies. The only previously published hypothesis regarding these clasping organs was refuted by the finding that species-specific portions of the male femur and tibia consistently meshed tightly with promin...
