Male size does not affect territorial behaviour and life history traits in a sphecid wasp
Article Abstract:
There is not a significant large male advantage in the European beewolf, Philanthus triangulum, in relation to territory quality, territory ownership, length of ownership, extent of scent marking, fat content and life span. This research considered whether the reproductive success of adult males is linked to body size in a way that would affect the allocation of parental investment. It was found that most measures of the magnitude of the size advantage were around one order of magnitude smaller than the critical value that would be required to alter the optimum investment per male offspring.

Female size affects provisioning and sex allocation in a digger wasp
Article Abstract:
The strong male bias in investments ratios in field populations of the European beewolf, Philanthus triangulum F. (Hymenoptera, Sphecidae), was investigated. The study examined the impact of the size of the female bee on provisioning and on the investment ratio of both individual females and the population. The findings indicated a positive correlation between female size and proportion of daughters produced. However, this relationship offers only a partial explanation for the overall variation in investment ratio.

Prey recognition by females of the European beewolf and its potential for a sensory trap
Article Abstract:
A key prediction for the sensory trap hypothesis for the evolution of the male sex pheromone in a solitary wasp, the European beewolf Philanthus triangulum is tested and the females hunt exclusively the honeybees, Apis mellifera as provisions for their larvae. The female European beewolves have a high sensitivity for (Z)-11-eicosen-1-ol that probably evolves in a context of prey hunting.
