To achieve reproductive success, crickets mate with multiple partners, defend against a variety of predators, and compete with fellow crickets. However, these behaviors have only been observed in controlled lab conditions, so to test environmental influences on natural and sexual selection, Rodríguez-Muñoz et al. set up a network of 64 motion-sensitive, infrared-equipped video cameras to monitor occupied field cricket burrows 24 hours a day. By tagging individual insects and profiling their DNA, the team was able to draw conclusions about mating behavior, reproductive success, and predation in the wild. In the first segment, corresponding author Tom Tregenza narrates several clips of burrow footage; the second segment shows how researchers monitored and analyzed cricket behavior.
