Season length and its associated variables can influence the expression of social behaviours, including the occurrence of eusociality in insects. Eusociality can vary widely across environmental gradients, both within and between different species. Numerous theoretical models have been developed to examine the life history traits that underlie the emergence and maintenance of eusociality, yet the impact of seasonality on this process is largely uncharacterized.

Tracking animals in social groups, however, remains challenging as most existing methods can either capture pose or robustly retain individual identity over time but not both.

We examined the population genomics and biogeography of the common palmfly , a dual mimic in which female wing colour patterns are either dark brown (melanic) or bright orange, mimicking toxic and species, respectively. As males always have a melanic wing colour pattern, this makes a fascinating model organism in which populations vary in sexual dimorphism.

Methods: A survey was conducted using a nurse and inspector administered questionnaire. 151 workers from 120 randomly selected firms participated in the survey.
