Richardiidae  The Richardiidae are a family of Diptera in the superfamily Tephritoidea. This small family consists of just over 30 genera and 175 species. Almost all species are neotropical. Generally, the biology of the richardiids is little known. Some of the larvae are plant feeders or saprophages in decaying plant material. One species, the pineapple fruit fly "Melanoloma viatrix", has been reported as a pest of pineapples. Most adults have some general features, conspicuously pictured wings, often with metallic blue or greenish colors on the body and legs, and a typical tephritoid ovipositor.
