Courtship feeding and repeated mating in Zorotypus barberi (Insecta: Zoraptera)

Article Abstract:

Females may repeatedly copulate with a preferred male so as to dilute the sperm from inferior males and thereby affecting the paternity of offspring as revealed by the mating behavior of Zorotypus barberi. The males are involved in an elaborate sequence of pre- and post-copulatory courtship, secreting a liquid substance and using it for alluring females to mate. The female only after being satisfied with the quality of mate, allow copulation. Females mating three or four times lay more eggs than those mating only once or twice implying that sufficient sperm supplies are needed for females to achieve full fecundity.

Sensory exploitation and the evolution of male mating behavior: a cladistic test using water mites (Acari: Parasitengona)

Article Abstract:

Results of a study indicate that male unionicolid mites show trembling behavior in response to the vibrations produced by the females of the species, during courtship. While, the vibrations produced by the female is a predatory behavior and is not related to courtship, the males' trembling behavior is a secondary sexual trait developed in response to the females behavior. The findings of the study support the sensory exploitation theory.

Sex identification and mating in the blue-ringed octopus, Hapalochlaena lunulata

Article Abstract:

A new study investigates the reproductive behavior of the blue-ringed octopus, Hapalochlaena lunulata, including male-female and male-male encounters. It is shown that males are unable to determine the sexual identity of potential mates before the hectocotylus is inserted and demonstrates that females pay an active role during copulation.
