For the parasitic natural enemies of the sting moth, the Chrysis shanghaiensis Smith and the Eurytoma monemae Rusch are generally documented in the literature. In recent years, we have found another species, Chlorocryptus coveanus Szepli-geti, whose parasitism is high in several places in our province after several years of observation (see table). Form: Female body length 15 ~ 18 mm, single-color red and yellow. Dark brown touch color, 34, shorter than the body, the first 7 to 10 is white.
