To get a general idea how to establish an introduced or indigenous species by rearing them in large numbers for release. To accomplish a wider distribution of a previously established species. To know the appropriate time to bring biological control methods to limit them
Lepidoptera: Noctuidae Identifying Characters: Forewings are grey to reddish-brown, with a complex pattern of creamy streaks and paler lines along the veins. Hind wings are greyish-white with greyish- brown margins.
