Using funtional trait analysis to explore cleptoparsite (Meloe franciscanus) host range across a large geographic mosaic: Chemical signals and temporal synchrony

We tested several functional traits and analyzed their role in defining cleptoparasite Meloe franciscanus (Coleoptera: Meloidae) host range across its geographic mosaic. Meloe franciscanus larvae cooperate to preempt the chemical communication system of its host bee by mimicking the sex pheromone of its female bee (Saul-Gershenz and Millar 2006). Chemical congruency and temporal synchrony traits were analyzed. Chemical congruency was a significant factor in host range, while temporal synchrony was determined to be a phenotypically plastic trait.
