Borrowed from French sérotine, from Latin sērōtina, a feminine form of sērōtinus (“late (in ripening, etc.); relating to the evening”) (referring to the bats being active late in the evening), from sērō (“at a late hour; too late”, adverb) (from sērus (“late, too late; slow, tardy”, adjective); ultimately from Proto-Indo-European *seh₁- (“lasting; long”)) + -tinus (suffix forming adjectives from adverbs relating to time).

Etymology 2
