Picture-winged flies are a diverse group of flies from multiple families (primarily Ulidiidae and Tephritidae) that share the characteristic of having elaborately patterned wings with bands, spots, or intricate markings. Many species perform distinctive wing-waving displays — slowly moving their patterned wings in a semaphore-like motion — which is used in territorial defense and courtship. In Arizona, picture-winged flies are found in a variety of habitats from desert washes to suburban gardens. Some species in the family Tephritidae are significant agricultural pests — the Mexican fruit fly (Anastrepha ludens) and other tephritid fruit flies attack citrus, stone fruits, and other crops. However, most picture-winged flies encountered in Arizona gardens are harmless or beneficial. Their wing patterns are thought to mimic jumping spiders, deterring predation.
