A study of the mating behaviour of males of the beewolf Philanthus zebratus revealed that in one population males display variability in mating tactics and that this variability is related to male body size. There was a tendency for large males to pa

Observations of wasp behavior indicate that male beewolves,Philanthus basilaris andP. bicinctus apply a “marking pheromone” to the leaves and stems of plants within their territories. We now provide direct evidence for the presence of volatile ch
