The response of adult beetles to light, temperature and humidity was investigated. Evidence is presented that the optimum combination of these environmental factors is a moderately high temperature (ï¿½25ï¿½C), moderately high humidity (ï¿½80% R.H.) and darkness. It was found that darkness is the dominating factor, which results in this species being nocturnal, and that a high humidity has a marked influence on its reactions.
