“…Laboratory studies which used real usurpation demonstrated that clypeal patterning has a null role in determining the outcome of usurpation contests: parasites with different facial patterns had no different chances of winning a contest with the host (Cini et al 2011;Green and Field 2011b). On the contrary, head size was the only determinant predictor of the likelihood of winning an usurpation contest (Cini et al 2011;Green and Field 2011b).…”

“…The likelihood that facial pattern evolved as sensory deception strategy by the parasite is also made less likely by the null fitness benefits associated to a particular clypeal patterning (Cini et al 2011;Green and Field 2011b). Laboratory studies which used real usurpation demonstrated that clypeal patterning has a null role in determining the outcome of usurpation contests: parasites with different facial patterns had no different chances of winning a contest with the host (Cini et al 2011;Green and Field 2011b).…”

“…First, the link between opponents facial patterns and aggressive responses has not been confirmed in the native range of P. dominula, where parasite-host interaction takes place (Green and Field 2011b;Branconi et al in prep). Moreover, the parasite pattern is not exactly the same as the host one: the black area is relevantly larger, it extends down to the mandibles and melanin is more uniformly distributed across the clypeus, thus largely reducing pattern disruption Green and Field 2011b). Finally, parasite facial pattern is not related to any fighting ability parameter taken into account so far (Cini et al 2015).…”

Social Recognition in Invertebrates

Social recognition, i.e. the ability to recognize and assign individual membership to a particular and relevant class, such as caste, dominance status, gender or colony, shapes the amazing organization of insect societies. Traditionally, it has been assumed that social recognition in social insects is mainly governed by chemicals. However, social insects also share information via many other sensory channels, and it has been recently demonstrated that visual signals can mediate several types of social recognition in some species of social wasps. Primitively social wasps, such as paper wasps of Polistes genus, are suitable models to investigate visual communication because their combs lack of envelops allowing light to produce visual cues, their colonies are small, they have a good vision, they show a remarkable individual within-colony colour variation and, finally, they show an intense social life based on social recognition. In this chapter we reviewed the role of visual cues in social recognition inside and outside social wasp colonies focusing both on the intraspecific and interspecific recognition contexts.

“…The decisions made by organisms are influenced by the perception of risks and benefits (Maynard-Smith 1982, McGill and Brown 2007, Orrock et al 2013, and aggression during confrontations often increases with the payoff of winning (Enquist and Leimar 1987, Green and Field 2011. In ant colonies, worker densities can change dramatically after partial losses of nesting areas or due to mortality during confrontations (Palmer et al 2000, Trager and Bruna 2006, Rudolph and McEntee 2015.…”

Experimental studies assessing the impact of demographic changes on aggression and inter‐group competitive outcomes in communities of social species are rare. This gap in our knowledge is important, not only because social species are foundational elements of many terrestrial ecosystems, but because interference competition among social groups often involves decision‐like processes influenced by demographic and environmental contexts. In East Africa, the symbiotic ant Crematogaster mimosae is a co‐dominant competitor that engages in high‐mortality, intra‐ and interspecific battles for sole possession of host trees. We manipulated worker density on C. mimosae Acacia host trees, and the colony's opportunity to expand onto neighboring trees to identify how these factors influenced colony‐level aggression, expansion success, and longer‐term survivorship. Worker density on focal trees was increased through translocation of domatia‐bearing branches, and was decreased using partial tree fumigations. We examined impacts of density manipulations on aggression and immediate expansion success under two different risk scenarios. We tied focal trees to either an experimentally emptied‐tree (low‐risk treatment), or to a C. nigriceps‐occupied tree (high‐risk treatment). Expansion success onto emptied neighbor trees was 100% for controls and increased‐density colonies, but only 50% for decreased‐density colonies, despite the fact that host trees are a limiting resource in this system. Success expanding onto trees occupied by a heterospecific competitor reached 36%, 40%, and 79% in decreased, control, and increased‐density trees, respectively. Our results show that changes in worker density due to disturbances or inter‐group battles have the potential to disrupt competitive hierarchies. Worker density manipulations also affected longer‐term colony persistence. Behavioral and genetic data revealed that 12 months after expansions 100% of the decreased‐density colonies, and 25% of control and increased‐density colonies, had been supplanted by neighboring opportunistic conspecifics. Intraspecific aggression may have lower costs in C. mimosae because aggressive colonies can incorporate workers or queens from defeated competitors. The unexpectedly high frequency of conflicts between conspecific C. mimosae, in combination with behaviors decreasing the cost of intraspecific competition relative to interspecific conflict, may create opportunities for the survival of subordinate competitors in this ant–plant system.

“…The clypeal patterns of the parasite may thus similarly function as signals of status, conveying the information of a high quality and highly dangerous bearer, finally decreasing host foundress's aggressiveness (Ortolani et al 2010, Green andField 2011b for P. semenowi). Alternatively, parasites may have evolved an independent quality signaling system, in which different facial pattern honestly mirror individual quality (e.g.…”
