Termite nests are complex group-level patterns created by collective building. The complexity of nest structures can be largely variable across termite species. As living nest structure influences inter-individual interactions and collective behavior, individual-level behavior should be adjusted to the species-specific nesting environments. However, it remains unknown how innate individual behavior can be variable across termite species. Here we show that movement of termite workers is strongly correlated with their nesting strategy. Our observation in a petri dish arena revealed that one-piece nesting termites, whose colony life is completed within a single piece of wood that serves as both their nest and food source, moved less distance than multiple-piece nesters or separate-piece nesters, who come out of their nests and forages beyond single food source. We further fitted truncated power-law and stretched exponential models to the distribution of move/pause durations and found movements of one-piece nesters are not limited by confined space. Additionally, we found strong thigmotaxis in the movements of multiple-piece nesters or separate-piece nesters. Further investigation into a larger number of species and more complex social contexts could provide insight into the evolutionary relationship between nesting structures and collective behavior in termites.
