Characteristics

The Western Pipistrelle is characterised by its erratic and butterfly-like flight. It is known to be the smallest bat in the United States; an adult male averages a length of 66 mm, the female is larger at 73 mm. They weigh around 3–6 grams. Their flight speed has been measured as 5 miles per hour (8 km/h), which is low compared to other bats but consistent with their size.

Distribution and habitat

The canyon bat is found in the western United States and Mexico, and is most common in deserts and dry brushland. They roost in small rock crevices.
