    Notes: Abstract D. birchii and D. serrata, two endemic Australian Drosophila species, have a copulatory courtship. The males of these species begin to court the female after mounting her and often go on with the courtship after the copulation is over. In the present paper we have described behavioral interactions between the male and the female and analyzed acoustic signals produced by the flies during courtship. Species differences were more pronounced in female than in male behavior. Variation within the species was obvious in the relative proportions of time the flies spent in different behaviors. Even though courtship took place nearly solely during copulation, some remains of precopulatory courtship were observed in both species. It is suggested that copulatory courtship exhibited by D. birchii and D. serrata flies is a derived rather than a primitive character.

    Copulatory Courtship in Drosophila birchii and D. serrata, Species Recognition and Sexual Selection (2000)

    Notes: Abstract Two endemic Australian Drosophila species, D. birchii and D. serrata, have a copulatory courtship, i.e., the males court the female mainly during copulation. In the present study we found the males of both species to mount their prospective mating partners selectively, exhibiting both sex and species recognition. The males began to sing after mounting the female, and they often exhibited also postcopulatory displays typical to copulatory courtship. D. birchii and D. serrata females discriminated against males which did not sing during mounting/copulation, which suggests that the females utilize cryptic female choice. Our findings raise the question of how widespread a phenomenon cryptic female choice is in Drosophila species.

    The effects of crowding on courtship and mating success inDrosophila melanogaster (1987)
    Springer
    Behavior genetics 17 (1987), S. 513-522 
    Details
    ISSN: 1573-3297
    Keywords: Drosophila melanogaster ; courtship ; crowding ; prestimulation ; evolution
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Psychology
    Notes: Abstract The mating times of single males and pairs of males were increased by crowding with virgin females but only at very high densities. Mating times were decreased by the presence of a second male. Quantitative analysis of courtship showed that prestimulation of females in crowded conditions influences mating. The pattern of male courtship was highly consistent across moderate levels of crowding. This suggests thatDrosophila courtships evolved in crowded conditions.
