Mayo and the plant species caterpillars were found on. Adult moths can be killed through freezing. Live moths or cater- pillars can be stored in a plastic container in a cooler on ice (at 0-10oC) for a week or more. Under these conditions live moths (if female) will frequently lay eggs, which can Carmacks Ross River then be reared to provide additional adults. Collecting/ killing samples of rare moths will not adversely affect their populations – only a tiny proportion of the total population will be affected, as long as the habitat continues to exist.
