Expulsion and consumption of male ejaculates by promiscous female euxesta eluta and euxesta mazorca (Diptera: Ulidiidae)
(Taylor & Francis Ltd, 2018-06)
While expulsion of male ejaculates by the females after copulation has been reported for various animal groups, expulsion followed by consumption of the expelled ejaculate is a rare behaviour outside spermatophylax-producing ...
The role of silk in courtship and communication in mygalomorph spiders: do males regulate their courtship in response to female mating status?
(Elsevier Science, 2019-10)
In spiders, pheromones are known to be responsible for attracting the opposite sex, eliciting male searching and courtship behaviors, as well as for synchronizing potential mates in space and time. Most spiders are ...
Chemical caressess: geographical variation of male sexual signals in a Neotropical scorpion
(Brill Academic Publishers, 2015-07)
Differences in sexual signals among species are common, and may influence mate recognition and reproductive isolation. In scorpions, behavioural mechanisms and other sexual signals involved in mate selection and reproductive ...
Reproductive biology of the nest building vizcacheras frog Leptodactylus bufonius (Amphibia, Anura, Leptodactylidae), including a description of unusual courtship behaviour
(British Herpetol Soc, 2017-01-01)
We describe the reproductive biology and sexual size dimorphism of a population of the vizcacheras frog Leptodactylus bufonius in the Brazilian Chaco. Reproduction takes place during the rainy months (September-March). ...
Reproductive biology of the nest building vizcacheras frog Leptodactylus bufonius (Amphibia, Anura, Leptodactylidae), including a description of unusual courtship behaviour
(2017-01-01)
We describe the reproductive biology and sexual size dimorphism of a population of the vizcacheras frog Leptodactylus bufonius in the Brazilian Chaco. Reproduction takes place during the rainy months (September–March). ...
Male wing fanning by the aphid parasitoid Aphidius ervi (Hymenoptera: Braconidae) produces a courtship song.
(2011)
We, herein, report evidence that wing fanning by the aphid parasitoid Aphidius ervi Haliday (Hymenoptera: Braconidae) constitutes a courtship song. Complete removal of the forewings or only the distal half of them reduced ...
Diversity and evolution of sexually dimorphic mental and lateral glands in Cophomantini treefrogs (Anura: Hylidae: Hylinae)
(Wiley-Blackwell, 2015-01-01)
We describe the structure and histochemistry of mental and lateral glands in a representative array of 28 species of five genera of the Neotropical hylid frog tribe Cophomantini. Structural diversity was coded in 15 ...
Differences in sexual behaviour of two distant populations of the funnel-web wolf spider Aglaoctenus lagotis
(Springer Tokyo, 2013-02)
Generally, sexual repertoire within a species is conserved, but frequencies of occurrence of sexual behavioral acts often vary, and wide geographic distributions may favor these variations. Aglaoctenus lagotis is distributed ...
Reproductive biology of dendropsophus haddadi (Bastos and pombal, 1994), a small treefrog of the atlantic forest
(2019-01-01)
Terrestrial reproduction has evolved at least 48 times in the evolutionary history of anurans. Most species in the genus Dendropsophus deposit eggs in water, but some, including Dendropsophus haddadi, lay terrestrial eggs. ...
