The NCHU Museum of Entomology, Department of Entomology, National Chung Hsing University is one of the important insect collections in Taiwan. This study aims to present a checklist of the determined diving beetles deposited at the NCHU Museum of Entomology, including 5 subfamilies, 9 genera, and 16 species.
This paper reports the first observation of the invasive Asian subterranean termite, Coptotermes gestroi (Wassmann, 1896), in eastern Taiwan. The known distribution of C. gestroi in Eastern Taiwan is mapped, and potential routes by which C. gestroi may further disperse throughout this region are also discussed.
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.
