摘要

螳螂目中偶有雄螳錯誤上背於異種雌螳的情形，可能肇因於費洛蒙或視覺線索的錯誤辨識，但鮮少雄螳錯誤上背於異種雄螳的情況。本文初次描述雄日本姬螳的錯誤上背於雄綠靜螳，同時也為臺灣產螳螂的第一筆野外錯誤上背之正式紀錄，並討論此現象發生之可能原因。

While heterosexual mismounting between heterospecific Mantodea is occasionally observed in the wild, it does not appear to be a common occurrence, and likely results from misidentifications of pheromone and/or visual cues by mantises. However, accounts of homosexual mismounting between heterospecific male mantises are extremely rare in the literature. The present study provides the first account (to our knowledge) of homosexual mismounting by a male Acromantis japonica Westwood, 1889 on a male Statilia nemoralis Saussure, 1870. This is also as the first formal record of mismounting between Taiwanese mantises in the wild. The possible causes of this rarely observed phenomenon are also discussed.
