📖 1. Overview

The Japanese pipistrelle is a small bat that roosts in crevices of human houses and buildings, ranging across the Russian Far East, Korea, Japan, China, Taiwan, and northern Southeast Asia.

🦴 2. Anatomy & Morphology

Its back is grayish brown and its belly is paler grayish brown, with thin, round-tipped ears. The tail membrane extends nearly to the tip of the tail.

🔍 3. Ecology & Behavior

It emerges 10–30 minutes after sunset to catch various insects around streetlights and similar places. It mates in October and stores sperm until fertilizing eggs after waking from hibernation; after about 70 days of gestation it gives birth to 2–4 young, and hibernates from late October to March.

🇰🇷 4. Connection to Korea

It is listed as Jipbakjwi (Pipistrellus abramus, Korean name) in the National List of Species of Korea (National Institute of Biological Resources (NIBR)) and has no national-level legally protected status. Once common, it has declined with the spread of concrete buildings, and Jeollanam-do and Gyeonggi-do have designated it as a protected species.
