Repeated shifts in social behavior within L. albipes. a Genetic principal component analysis of six populations: three social (blues and greens) and three solitary (reds and oranges). b Population tree. Each dot represents an individual (n = 143). Analyses were run using LD-pruned SNPs (n = 688,836). Both the PCA and the population tree demonstrate that social and solitary forms are not incipient species; instead, the multiple groupings of social and solitary populations are consistent with repeated shifts in social behavior within L. albipes, likely the result of local adaptation
