); the water quality tended to be alkaline (pH = 9.04). In the laboratory, the mature nymphs quickly completed the molting process on the water surface from 9 pm to 12 pm at night. The subimago stage persisted until the third noon or afternoon, with the observed lifespan of imagoes being about 3–4 days.
