AbstractThis study compares the metacercariae of a ‘pygmaeus’ microphallid discovered in Littorina saxatilis from the coast of Northern Ireland with the metacercariae of Microphallus piriformes and M. pygmaeus from the same species of gastropod mollusc from Arctic Russia. Light and scanning electron microscopy were used to provide morphometric and surface details for descriptions of the organisms concerned. Comparison and statistical analysis of the results established that the species from Northern Ireland was M. piriformes and not M. pygmaeus as had previously been assumed. It dearly indicates the need for critical assessment of the accuracy of literature dealing with the occurrence of ‘M. pygmaeus’ in both intermediate and final hosts.

Ample anecdotal and some scientific evidence suggests that men who enter a relationship feel that they are flirted with more frequently than before they had a partner. This phenomenon has been interpreted as a form of mate choice copying; the idea that females prefer males that are in a relationship with another female. In two samples (N = 271 and N = 396) we replicate that people indicate that flirting increased after entering a relationship. However, on a more absolute measure (how often people feel they are flirted with), we did not find that those in a relationship felt to be flirted with more than those without one. Our findings cast doubt on the interpretation that ours (and similar) findings are support for mate choice copying, and we argue that alternative explanations should be considered.
