R scandens is well-known as a host plant fer NL Perni xin Honshu, Shikoku and Kytishu. Key words Sesiidae, AJbkona mbra, host plant, Ryukyus. Albkona ntbra Arita and Tosevski, 1992 was recently describe dfrom three specimens (on emale and two females )taken with net on Amami-Ohshima and Okinawa-jima Islands t,he Ryukyus, Japan ,without any record of host plant (Tosevsk aind Arita ,1992 ; Arita,1994). During our collecting trip to Okinawa-jim aIsland in Jul y1994, we found a few damages of the stems and vines of thederia scandens (Rubiace aien)jure dby Sesiidae ,similar to Nbhona Perni h(rLeech 1,889) , A littl ebit later ,in the beginning of September, this time on Amami-Ohshima Island, we observed numerous young larvae on the same host plant, but having no chance to breed such young instar sef clearwing rnoths, we did not collect any.In the beginning of Januar y1995 ,Mr M. Kimura sent us several stems of R scandens with clearly visible galls derivin gfrom Okinawa-jima Island .Insid ethese galls, we found a few medium-sized larvae of Sesiidae .After keeping them in the laborator yat a temperature about 280C ,two females of Nbfeona rabva successfully emerged. Thus, i:iteder iscnandens (Rubiacea ei)s the host plant both of AJbkona rubra and of AJI Pemix, Larval biology of the second species is werl-known (Yano ,1961 ; Arita et al,, 1994) . At the present time, we can cite that the Iarval biology of N rubra is very similar to that of N Pernix in many detail s(shap eof larva lgall ,very short larva lgarlery, pupation taking place in a very tough, black cocoon), but it differ sclearly in that the larva of N rabra hibernate sin a larva lgallery (i na tough cocoon in N Pernix )and constructs such a tough cocoon only in spring.
