Post‐mounting courtship and the neutralizing of male competitors through “homosexual” mountings in the fly Hydromyza livens F. (Diptera: Scatophagidae)
Abstract:Post‐mounting courtship behaviour of a 6–8 mm long scatophagid fly Hydromyza livens which lays its eggs in yellow water lily ( Nuphar lutea ) is described and analysed. Enigmatic male–male encounters are described, along with lengthy “homosexual” mounting behaviour. A possible interpretation of both types of behaviour is given, with reference to their adaptive significance and the special problems encountered by males in locating females.
