The family Syrphidae constitutes one of the largest families of the order Diptera. The individuals are medium to large in size and may be bare, pilose, or covered with thick pile. Some species are metallic blue or green in color, while others are vividly marked with yellow bands, spots, or stripes on all parts of the body, but especially on the abdomen.
