📖 1. Overview
The Asian Long-fingered Bat is a cave-dwelling bat whose colony sizes vary from fewer than 20 individuals to millions.
🦴 2. Anatomy & Morphology
Its wings are very narrow and long, and its body is covered in soft, short fur. The forearm measures 41–50 mm, and the second phalanx of the third finger is about 3 times as long as the first phalanx.
🔍 3. Ecology & Behavior
It mates in mid-October (month 10), but delayed embryonic development during hibernation extends gestation to about 260 days, giving birth to a single pup between mid-June and early August (months 6–8). When migrating, it flies in flocks at speeds similar to swallows.
🇰🇷 4. Connection to Korea
On the National List of Species of Korea, its domestic distribution covers all of Korea. Males and females live separately when females gather to give birth, and they sometimes roost mixed with the Greater Horseshoe Bat.
