Piti, April 30; Yigo, Oct. 21, Nov. 8, all reared by Swezey. One specimen in Bishop Museum, Fullaway, 1911. The work of the larvae was seen in many places. An ichneumonid ( Echthromorpha conopleura Krieger ) issued from some of the pupae. This widely distributed moth occurs from west Africa through south Asia to Japan , and the Malayan and Australian regions. It is in Samoa and no doubt other Pacific island groups. In some countries its larvae feed on cotton, but in Guam it is a leafroller on pago ( Hibiscus tiliaceus ). We found it often abundant, many of the leaves being partially rolled up for hiding places. The pupa was formed in the same place.
