Arkansas is home to a diverse array of bat species, each with unique behaviors, habitats, and roles in the ecosystem. Whether you’re a nature enthusiast, a homeowner concerned about bats in your attic, or simply curious about these fascinating creatures, this list covers the most common and noteworthy bats found across the state. Learn about their appearances, habits, and why they matter so you can better appreciate and coexist with Arkansas’s native bats.
Eastern Red Bat (Lasiurus borealis)
The Eastern Red Bat is easily recognizable by its vibrant, rusty-red fur that covers its entire body. It is a solitary species that prefers deciduous forests and roosts in the foliage of trees during the day. Known for its impressive migration habits, the Eastern Red Bat travels thousands of miles annually, making it a vital part of the local ecosystem by controlling insect populations.
Big Brown Bat (Eptesicus fuscus)
The Big Brown Bat is one of Arkansas’s most common and robust species, measuring about 4.5 to 5.5 inches in wingspan. It has dark brown fur and is often seen roosting in buildings, caves, or tree hollows. Its strong, high-frequency echolocation helps it hunt a wide variety of insects, including beetles and mosquitoes, making it a natural pest controller.
Little Brown Bat (Myotis lucifugus)
The Little Brown Bat is a small, agile species with a wingspan of about 8-10 inches, characterized by its brown fur and relatively plain appearance. It prefers roosting in tree bark, buildings, and caves, especially during the summer months. This species is crucial for maintaining insect populations and has been significantly affected by white-nose syndrome, a fungal disease impacting bat populations nationwide.
Northern Yellow Bat (Lasiurus intermedius)
The Northern Yellow Bat is notable for its striking yellowish fur, which provides excellent camouflage in its preferred habitats of open woodlands and forest edges. It is a solitary species that roosts in trees and is active primarily at dusk and dawn. Its diet mainly consists of moths and beetles, contributing to pest control in Arkansas’s ecosystems.
Hoary Bat (Lasiurus cinereus)
The Hoary Bat is distinguished by its long, frosted-gray fur and large size, with a wingspan of up to 15 inches. This migratory species prefers forested areas and often roosts in tree canopies. It plays a significant role in controlling night-flying insects and is one of the few bats that often roost in groups, especially during migration periods.
This tiny bat measures just 3-4 inches in length, with dark fur and small feet, hence the name. It favors rocky caves and crevices for roosting and feeds mainly on small insects like flies and beetles. Despite its small size, it is vital for insect population regulation in the mountainous and rocky regions of Arkansas.
Tri-colored Bat (Perimyotis subflavus)
The Tri-colored Bat is named for the three distinct fur color bands: brown, yellow, and gray. It roosts in tree cavities, caves, and buildings, especially during hibernation. Its presence indicates healthy forest and cave ecosystems, and it is a key predator of moths and beetles, helping to control crop pests.
Brazilian Free-Tailed Bat (Tadarida brasiliensis)
Although more common in southern states, the Brazilian Free-Tailed Bat has been spotted in Arkansas, especially during migration. It is known for its long, narrow wings and incredibly fast flight speeds. This species roosts in caves, bridges, and buildings, and is highly effective at consuming large quantities of moths and beetles, making it an important species for pest management.
Evening Bat (Nycticeius humeralis)
The Evening Bat is a small, brown bat that often roosts in tree hollows, buildings, and bat boxes. It emerges at dusk to hunt insects such as beetles, moths, and flies. Its adaptability to human structures makes it a common sight in Arkansas towns and rural areas, helping naturally control pest insects around homes.

When selecting or identifying bats in Arkansas, consider key factors such as size, fur color, habitat preference, and roosting habits.

For conservation or removal purposes, understanding the species’ roosting needs and behaviors helps ensure respectful and effective interactions. Always consult local wildlife experts before handling or relocating bats, as many species are protected and sensitive to disturbance.
