For This Beetle, ‘Date Night’ Comes Every Other Day (IMAGE)
Caption
Holotrichia parallela, the large black chafer beetle, is a serious agricultural pest in Asia. The beetles have an unusual mating strategy, with females emerging every other night and releasing a pheromone scent to attract males. A new study by researchers at UC Davis and in China shows that the male beetles' ability to detect female pheromones is also on a 48-hour, or circabidian, cycle.
