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.
