Visual signals of individual identity in the wasp Polistes fuscatus.
Individual recognition is an essential component of interactions in many social systems, but insects are often thought incapable of the sophistication necessary to recognize individuals. If this were true, it would impose limits on the societies that insects could form. For example, queens and workers of the paper wasp Polistes fuscatus form a linear dominance hierarchy that determines how food...
متن کاملDivision of labour in colony defence against vertebrate predators by the social wasp Polistes fuscatus.
In this study I examined how the paper wasp, Polistes fuscatus, defends a colony when faced with a vertebrate attack. I looked for a division of labour in defensive behaviour within a colony and examined whether this behaviour changes over the colony cycle. The colonies were presented with a model of an adult red-winged blackbird, Agelaius phoeniceus, and a speaker that vibrated the comb. There...
متن کاملAntennal Drumming, Trophallaxis, and Colony Development in the Social Wasp Polistes fuscatus (Hymenoptera: Vespidae)
Parental care is widespread among both vertebrates and invertebrates. In some species, the parents provide the young only with protection from predators and ⁄or parasites, but in most others the adults provide nutrients for their immature offspring. The latter context has led to the evolution of social behavior in a few groups, notably in some of the mammals and in the social Hymenoptera (Alexa...
متن کاملSpecialized visual learning of facial signals of quality in the paper wasp, Polistes dominula
Some primates and one species of paper wasp recognize faces using specific processing strategies to extract individual identity information from conspecific faces. Explanations for the evolution of face specialization typically focus on the complexity associated with individual recognition because all currently identified species with face specialization use faces for individual recognition. In...
متن کاملRearing conditions influence quality signals but not individual identity signals in Polistes wasps
Given the diversity of animal signals, there has been recent interest in categorizing signals into probable functions according to their properties. For example, models predict that signals of quality should be costly and condition dependent, whereas signals of individual identity should be cheap and expressed independently of condition. Here, we test these predictions by comparing the conditio...
