Analyzing the Flight Patterns and Behavior of Dragonflies Engaged in Aerial Territory Battles

It has previously been determined that male dragonflies occupying the most suitable territory within a habitat have a higher flight-muscle ratio (FMR) than those occupying poor territories, but it is unknown how this increased FMR relates to their flight patterns. This study examined the flight patterns of dragonflies engaged in aerial territory battles to investigate differences in maneuverability between winners and losers. 3D video data of dragonflies interacting in a natural habitat was analyzed for territorial flights. Winners showed a lower maximum angular velocity compared to losers.
