"Long-eared Myotis," Wikipedia, the free encyclopedia. The long-eared myotis is an insectivore, whose robust molars and highly placed articular process allow it be especially good at hunting beetles. A high articular process allows for more crushing force while the bat is chewing. This is advantageous because it allows penetration of the hard carapace found on many beetles. The long-eared myotis feeds by both substrate-gleaning of the ground or of trees, and by aerial-hawking. Prey is always detected through echolocation when aerial-hawking. When gleaning, the bats use echolocation less often and at a lower frequency due to the energetic cost of echolocation calls.
