Abstract:

A specimen of an extremely rare sphingid Tinostoma smaragditis, endemic to the island of Kauai, Hawaii was collected in late July 1992. prior to expiring, it oviposited 56 eggs of which 79% were fertile and enclosed, providing a brief opportunity to discover its unknown, larval host-plant(s). Almost 140 species of plants, many endemic to the Hawaiian Islands, were offered to the larvae through a combination of 3 methods. Among the plants was the species upon which the adult was found as well as suspected host plant species. Larvae did not respond to any plant species tested; larvae attempting to feed or actually feeding were not observed. Thus, the host-plant(s) remains unknown. Names of plant species offered to the larvae are provided and are considered unlikely host-plants given the lack of immature response
