“…Thus, studies on species whose individuals exhibit more alternative or facultative social behaviour (compared to species with predetermined caste differentiation) may help to provide more clear evidences of how advanced forms of sociality may have evolved (Dunn & Richards, 2003;Peso & Richards, 2010;Prager, 2014;May-Itzá et al, 2014;Rehan et al, 2014;Andrade et al, 2016).…”

Reproductive conflict expressed as aggression is common in social Hymenoptera. In eusocial species, as in honeybees, several mechanisms alleviate the conflicts and reduce aggressive interactions. Unlike their sister group, the orchid bees do not exhibit eusociality. Instead, most of the species seem to have lost sociality and some species have retained vestigial social behaviour. In the current study we investigated the aggressive interactions of females of Euglossa annectans Dressler through five generations of phylopatry and reuse of the natal nest. Although network analysis indicates that central individuals, those with more interactions, were more commonly the aggressors and others were more commonly the recipients, multiple attacks and several potential dominant female within the nest indicated a labile sociality. This suggests that there is an unstable social hierarchy in the species. Euglossa annectans, despite having overlapping generations, during which several individuals share a nest, there is no division of labour into reproductive and interactions are often competitive. Aggressive behaviours conducted by multiple fertile females were often followed by egg, larvae or pupae replacement.

“…Even in the facultatively social Xylocopa virginica (L.), PASS is not frequently performed between both NMs and NNMs [Peso and Richards, 2010]. Also in C. rubida PASS is rarely displayed by both NMs and NNMs (Table III).…”

Females of communal and eusocial Hymenoptera differ greatly in the treatment of conspecifics: communal species lack the nest membership-bias treatment via nestmate (NM) recognition, which is typical of eusocial Hymenoptera. Therefore, an analysis of social interactions can suggest whether a given bee or wasp is communal or eusocial. For this reason, we observed females of the digger wasp Cerceris rubida in experimental dyadic encounters. Because this species had previously been labeled "communal," we expected to find little evidence of a NM bias with respect to cooperation or aggression when paired with NMs and non-nestmates (NNM). Contrary to expectation, females were highly cooperative toward NMs and highly aggressive toward NNMs. Variation in the intensity of aggression toward NNMs partially stems from the degree to which the paired females differed in size. From these results and quantitative comparisons with studies on solitary, communal, and eusocial bee species, it appears that C. rubida has a more complex social organization than previously believed and, in particular, that females of this species exhibit NM recognition, a trait associated with eusociality.

“…A few weeks later in spring, females also emerge to forage for larval provisions (May and June). In our study population in southern Ontario, about 10% of females nest solitarily, but most are social, living in groups of two to five adult females (Peso, 2008). The nature of colony social organisation is not clear.…”

“…Most bees overwinter in their natal nests. In spring (April or May), males emerge from the nests in which they overwintered to guard territories centred above the nest substrate, returning to nests at night (Peso and Richards, 2010). A few weeks later in spring, females also emerge to forage for larval provisions (May and June).…”

Not all who wander are lost: nest fidelity in Xylocopa virginica examined by mark recapture

Relocation to novel nests (sometimes called drifting) in flying Hymenoptera is often interpreted as the result of navigation error and guard bees erroneously admitting foreign individuals into the nest. We studied nest fidelity and nest relocation of both females and males in a nesting aggregation of Xylocopa virginica in southern Ontario, Canada, where females can nest either solitarily or socially. Adult female and male bees were trapped at nest entrances, individually paint marked, and then released. Subsequent recapture patterns were used to assess nest fidelity: that is, how faithful individuals were to their home nest and how often they moved to another nest. Bees were considered to have relocated if they were recaptured in a nest different from the one in which they were initially trapped, indicating that they had spent at least one night in a new nest. Some females were only captured in one nest, some occasionally moved to new nests, temporarily or permanently, and a few were never caught in the same nest twice. In addition, females relocated to nests that were further away in 2007 when population density was low, suggesting that they seek out and claim nesting spaces when they are available. Males relocated more frequently than females, with most drifting from nest to nest in no obvious pattern. This indicates that males spend the night wherever space is available or in nests nearest to their territories. This study reveals that for both female and male X. virginica, nest membership is not as stable as once thought.
