摘要

本文自臺東縣蘭嶼記錄臺灣新記錄種灰蝶，即曲波灰蝶Catopyrops ancyra。 Catopyrops屬蝴蝶過去在臺灣地區尚未有記錄，而本文報告之樣品經比較研究暫判定係屬於曲波灰蝶分布於婆羅洲及菲律賓地區之亞種C. ancyra almora (Druce)。蘭嶼產的本種判斷係來自菲律賓地區，但有可能業已在該島立足，由於曲波灰蝶可能以蕁麻科之落尾麻、豆科之蘇木屬以及大戟科之饅頭果屬為幼蟲寄主，因此將來有侵入臺灣本島及其他東部離島的可能。

並列摘要

Catopyrops, a genus of Lycaenidae previously unrecorded to Taiwan, was found from Lanyu, an island southeast of Taiwan. The collected samples, identified as C. ancyra almora, presumably invaded from the Philippines by natural pathways. This species might have established successfully because samples were being obtained four years after its discovery at Lanyu. Possible larval hosts include Pipturus arborescens (Urticaceae), Caesalpiniαspecies (Fabaceae) and Glochidion species (Euphorbiaceae), thus this butterfly has the potential to invade the main island of Taiwan and the other islands along the eastern coast of Taiwan.
