Indian False Vampire Bat Feeding on Myotis
-
摘要: 2004年12月10日,在广西南宁地区马山县金伦洞捕到2只雄性印度假吸血蝠(Megaderma lyra: Megadermatidae, Chiroptera),分析其中的胃容物,发现有蝙蝠的残遗物,包括牙齿、后足、骨骼、毛发(棕黄色);未发现昆虫残遗物。通过对残遗物中牙齿(上颌齿式:2.1.3.3)的鉴定,与蝙蝠科鼠耳蝠属(Myotis)的齿式一致,因此确定印度假吸血蝠捕食了鼠耳蝠属的蝙蝠。Abstract: We captured two Megaderma lyra (Megadermatidae, Chiroptera) males in Jinlun Cave, Mashan County, Guangxi Province on December 10, 2004. The two males were killed for another experiment, however we collected their stomachs for examination. The stomach contents of these two bats were examined and the remains of other bats species were found, including dentes, hindfoot, skeleton and hair. By careful examination of the dentes we identified that the upper-dental formula was 2.1.3.3. This formula coincided with Myotis, confirming that the Indian false vampire bat feeds on Myotis. We did not find any remains of insects in these two samples.
