Pipistrelle is a type of small bat commonly found in Europe. However, if you're looking for other terms to refer to these creatures, there are a few synonyms to consider. For example, the word "microbat" is often used as a general term for smaller bat species, including the pipistrelle. Another term you might come across is "flittermouse," which is an old English term for bats that emphasizes their fluttering flight patterns. Finally, in some regions, pipistrelles may be referred to as "dusk bats," "twilight bats," or even "evening bats," since they tend to emerge from their roosts around sunset and fly around during the twilight hours.
