Biting flies are commonly known to be attracted to dark-colored clothing, but few studies have investigated the underlying color preference of these flies. A recent study conducted by researchers from the University of Sydney employed artificial neural network (ANN) modeling to analyze the visual preferences of biting flies. The ANN model was trained using thousands of images of different colors and patterns, and the results revealed that biting flies exhibit a strong preference for blue objects. The research suggests that this color preference may be linked to the flies' natural prey, such as insects and birds, which often have blue or blue-green coloration. This study provides valuable insights into the behavior of biting flies and could help develop more effective strategies for controlling these pests.
