(Muscidae) It is 6-7 mm long, with a shiny head and chest, wider than the abdomen, which is oval and black, with white edges on the side, crescent-shaped white stripes near the base, and four pairs of white spots near the abdomen. The second spot is large and curved horizontally, and the third to fourth spots are the smallest, with thick black feet and hairy feet, but the stripes vary greatly among individuals. There are two species of this genus, and the other is the orange fly tiger, which is called the black cat jumping spider in Chinese mainland. It has a yellow-brown abdomen, a black longitudinal belt in the center and splashes of different lengths and thicknesses on both sides. This species is distributed in low-altitude mountainous areas and inhabits low branches and leaves, which is not common.
