“…In one study, researchers found that the willingness of individuals to share or withhold information from competitors is influenced by the composition of the social environment, which they coined "audience effects" (53). In Drosophila, audience effects may explain why flies signal fertile oviposition sites (16,54) and the presence of predators to naïve flies (18). In the wild, flies may readily organize and transmit valuable information about their environment if the benefits of cooperation exceed the cost of competition.…”

Animals interact with each other in species-specific reproducible patterns. These patterns of organization are captured by social network analysis, and social interaction networks (SINs) have been described for a wide variety of species including fish, insects, birds, and mammals. The aim of this study is to understand the evolution of social organization inDrosophila. Using a comparative ecological, phylogenetic, and behavioral approach, the different properties of SINs formed by 20 drosophilids were compared. We investigate whether drosophilid network structures arise from common ancestry, a response to the species’ past climate, other social behaviors, or a combination of these factors. This study shows that differences in past climate predicted the species’ current SIN properties. The drosophilid phylogeny offered no value to predicting species’ differences in SINs through phylogenetic signal tests. This suggests that group-level social behaviors in drosophilid species are shaped by divergent climates. However, we find that the social distance at which flies interact correlated with the drosophilid phylogeny, indicating that behavioral elements of SINs have remained largely unchanged in their evolutionary history. We find a significant correlation of leg length to social distance, outlining the interdependence of anatomy and complex social structures. Although SINs display a complex evolutionary relationship across drosophilids, this study suggests that the ecology, and not common ancestry, contributes to diversity in social structure inDrosophila.

“…Flies display collective feeding strategies and collective escape responses, and they communicate the presence of predators and parasites (17). They engage in social learning (18)(19)(20) and display aggression (21). When a diseased individual is present, group dynamics are altered (22).…”

“…In one study, researchers found that the willingness of individuals to share or withhold information from competitors is influenced by the composition of the social environment, which they coined “audience effects” [46]. In Drosophila , audience effects may explain why flies signal fertile oviposition sites [6, 7] and the presence of predators to naïve flies [10, 11]. In the wild, flies may readily organize and transmit valuable information about their environment if the benefits of cooperation exceed the cost of competition.…”

“…We speculate that social communication across drosophilids is conserved, given that drosophilids are known to encounter and interact with other species [47]. Recent work uncovered that drosophilids can socially signal the presence of predators to an unrelated heterospecific species [11], suggesting that flies communicate in “dialects” with each other. When considering complex social organization behaviours, the ecological pressures of a species’ environment play a large role in shaping these phenotypes.…”

“…Despite its common label as a solitary insect, D. melanogaster displays a variety of social and collective behaviours. These include coordinating egg-laying sites [6, 7], trans-generational mate preference [8], collective feeding strategies [9], communicating the presence of predators/parasites to group members [10, 11] and collective escape responses [12]. Additionally, groups of D. melanogaster socially interact in a group setting that is structured and non-random.…”

Cultural norms, collective decisions, reproductive behaviour, and pathogen transmission all emerge from interaction patterns within animal social groups. These patterns of interaction support group-level phenomena that can influence an individual's fitness.The aim of this study is to understand the evolution of social organization in Drosophila.Using a comparative ecological, phylogenetic and behavioural approach, we studied the different properties of social interaction networks (SINs) formed by 20 drosophilids and the different ways these species interact. We investigate whether animal network structures arise from common ancestry, a response to the species' past ecological environment, other social behaviours, or a combination of these factors. We demonstrate that differences in past climate predicted the species' current SIN properties. The drosophilid phylogeny offered no value to predicting species' differences in SINs through phylogenetic signal tests. This suggests group-level social behaviours in drosophilid species are shaped by divergent climates. However, we find that the distance at which flies interact correlated with the drosophilid phylogeny, indicating that behavioural elements that comprise SINs have remained largely unchanged in their recent evolutionary history. We find a significant correlation of leg length to social distance, outlining the interdependence of anatomy and complex social structures.Although SINs display a complex evolutionary relationship across drosophilids, this study provides evidence of selective pressures acting on social behaviour in Drosophila.We speculate that conserved molecular mechanisms may be shared across drosophilids deep in their evolutionary history, similar to other pervasive mechanisms, like biological clocks.
