Coercive mating, fluctuating asymmetry and male mating success in the dung fly, Sepsis cynipsea
Article Abstract:
Male dung flies guard their mates before engaging in copulation and the males that are able to hang on to the larger females after copulation are often the most successful. A comparison of male foretibiae, used to hang on to the females, was conducted to identify possible morphological differences. The results showed that males with more symmetrical foretibiae are relatively more sexually attractive to females because of their competitive ability to hang on to the females during copulation.

Female choice and manipulations of forceps size and symmetry in the earwig Forficula auricularia L
Article Abstract:
Four UK populations of the European earwig, Forficula auricularia, were studied to determine the influence of symmetry and size of male secondary sexual traits on female preferences. Independent manipulations of the forceps length revealed that females preferred males with longer forceps. On the other hand, manipulations of asymmetry showed that females are not very particular about asymmetry, thereby confirming that female preference is a factor in sexual dimorphism in these animals.

The role of cuticular hydrocarbons in male attraction and repulsion by female Dawson's burrowing bee, Amegilla dawsoni
Article Abstract:
The behavioral and chemical assays are used to examine the potential role of cuticular hydrocarbons (CHCs) in sexual communication in a solitary burrowing bee, Amegilla dawsoni. The results obtained from the experiments that were conducted in the late July and early August 2001 at the emergence site on a 100-m stretch of compacted dirt track on the outskirts of Carnarvon, Western Australia, are reported.
