Female mating frequency in a wild population of scorpionflies (Panorpa germanica, Panorpidae, Mecoptera)

In this study, we investigated mating frequencies of female scorpionflies Panorpa germanica in the field using two different experimental approaches. First, the mating status of wild‐caught females was estimated on the basis of sperm numbers present inside their sperm storage organs. Secondly, the number of mating partners wild‐caught females must have had was inferred from mother‐offspring analyses of a polymorphic microsatellite locus. Our results suggest a very low mating frequency of wild female P. germanica. Consequently, the risk of sperm competition is rather low in this species. The relevance of female mate choice in relation to the low mating frequency is discussed.
