Its ears are 31–33 mm long, well over half the head-and-body length (48–50 mm). The forearm measures 40–42 mm.
🔍 3. Ecology & Behavior
It feeds mainly on moths and mosquitoes, catching them both in flight and by gleaning them from leaves. It roosts in small groups of a few dozen or fewer in crevices of old trees, and hibernation in caves has been recorded in Primorsky Krai.
