About the Pallid Bat
The pallid bat (Antrozous pallidus) is a species of bat that ranges from western Canada to central Mexico. It is the sole species of its genus and is closely related to Van Gelder's bat (Bauerus dubiaquercus), which is sometimes included in Antrozous. Although it has in the past been placed in its own subfamily (Antrozoinae) or even family (Antrozoidae), it is now considered part of the subfamily Vespertilioninae and the tribe Antrozoini.
It is the state bat of California. Pallid bats have a head and body length of approximately 2.75 inches (6.2-7.9 cm), forearm length of approximately 2.1 inches (4.5–6 cm), a tail of approximately 1.75 inches (3.9-4.9 cm), and a wingspan of 15-16 inches (38–40 cm). They weigh 14-25 grams. These bats are large, with long forward pointing ears (over 2.5 cm). Fur is pale at the roots, brown on their back, with a light underside. Pallid bats have a blunt piglike snout. The dental formula for pallid bats is 1.1.1.32.1.2.3 × 2 = 28.

The bone also has a characteristic downward 'dip' around the midpoint, with... Wikipedia →
