Mississippi is home to a diverse array of bat species, each playing a vital role in local ecosystems by controlling insect populations and pollinating plants. Whether you’re a wildlife enthusiast, a homeowner concerned about bats in your attic, or simply curious about the creatures that thrive in the Magnolia State, this list covers the most common and noteworthy bat species you’ll encounter. Here are ten types of bats in Mississippi, with detailed insights into what makes each one unique and why they matter.
1. Big Brown Bat (Eptesicus fuscus)
The Big Brown Bat is one of the most widespread and commonly seen bats in Mississippi. Recognizable by its large size—about 4.5 to 5 inches in length—and rich brown fur, it often roosts in buildings, tree cavities, and bridges. Its diet primarily consists of beetles, moths, and other insects, making it a natural pest controller. This species is particularly valuable for homeowners because it helps reduce mosquito and fly populations around homes and farms.
2. Eastern Red Bat (Lasiurus borealis)
The Eastern Red Bat is easily identified by its striking reddish-orange fur and white patches on its shoulders and around its face. It prefers roosting in tree foliage, especially during the summer months, but can also be found roosting in buildings or under leaves. Known for its solitary behavior, this bat migrates south for the winter and plays a crucial role in controlling moths and beetles. Its vibrant color makes it a favorite among wildlife watchers.
3. Tri-colored Bat (Perimyotis subflavus)
The Tri-colored Bat, formerly called the Eastern Pipistrelle, is notable for its small size—about 3 inches long—and its tri-colored fur, which features a darker back, a lighter middle section, and a yellowish belly. It often roosts in tree hollows, caves, and buildings, especially in the summer. This species is vital for insect control in forested and suburban areas but is currently listed as endangered in some parts due to white-nose syndrome.
4. Southeastern Myotis (Myotis austroriparius)
The Southeastern Myotis is a medium-sized bat, reaching about 3.5 inches in length, with a brownish-gray coat and a distinctive face with large ears. It primarily roosts in hollow trees, cypress knees, and abandoned buildings near water bodies like rivers and lakes. Its diet mainly includes aquatic insects, making it an important species for maintaining healthy aquatic ecosystems. Conservation efforts are crucial as habitat loss threatens their populations.
5. Northern Yellow Bat (Lasiurus intermedius)
The Northern Yellow Bat is a less common species in Mississippi, distinguished by its bright yellowish fur and white wing patches. It prefers dense forests and roosts in tree foliage, especially during migration periods. Its diet mainly consists of moths and beetles, and it plays an essential role in controlling these insect populations. Because of its rarity, spotting a Northern Yellow Bat is considered a special event for wildlife enthusiasts.
6. Evening Bat (Nycticeius humeralis)
The Evening Bat is a small, adaptable species, measuring around 3 inches long, with a brownish-gray coat. It often roosts in tree cavities, buildings, and bridges, especially in the southeastern U.S. Its nocturnal foraging focuses on moths, beetles, and other insects, making it an important natural pest control agent. Its ability to thrive in urban and suburban environments makes it a common sight in Mississippi communities.
7. Indiana Bat (Myotis sodalis)
The Indiana Bat is a federally endangered species, recognized by its glossy black fur and small size—about 3 inches long. It hibernates in caves and mines during winter and forages over forests and water during warmer months. The species is highly sensitive to habitat disturbance, especially during hibernation, making conservation efforts in Mississippi crucial for its survival. Protecting its roosting sites benefits the entire ecosystem.
8. Little Brown Bat (Myotis lucifugus)
The Little Brown Bat is one of North America’s most common bats, measuring approximately 3 inches long with a dark brown fur. It roosts in buildings, tree cavities, and caves and feeds mainly on moths, beetles, and flies. Its high insect consumption helps control agricultural pests and supports local ecosystems. Sadly, populations have declined due to white-nose syndrome, making awareness and conservation vital.
9. Rafinesque’s Big-eared Bat (Corynorhinus rafinesquii)
The Rafinesque’s Big-eared Bat is distinguished by its exceptionally large ears—up to an inch long—and soft, brown fur. It prefers roosting in hollow trees, caves, and old buildings, especially in southern Mississippi. Its diet includes moths and beetles, and it is particularly sensitive to habitat destruction. Protecting mature forests and old structures helps conserve this unique species.
10. Southeastern Bent-wing Bat (Miniopterus schreibersii)
While not commonly found in Mississippi, the Southeastern Bent-wing Bat has been recorded in some southern regions as a rare migrant. Recognizable by its long, narrow wings and distinctive bent shape, it roosts in caves and mines. Its diet includes small insects, and it contributes to insect population control during migration. Due to its rarity, sightings are significant for bat researchers and conservationists.
How to Choose
When selecting which bat species to focus on or attract, consider their habitat preferences, size, and dietary needs. If you’re interested in pest control, species like the Big Brown Bat and Little Brown Bat are excellent choices due to their insect-eating habits. For conservation purposes, understanding the habitat requirements of endangered species like the Indiana Bat is crucial. Additionally, consider whether you’re observing for educational purposes or wanting to support local bat populations—this will influence which species you prioritize.
Frequently Asked Questions
Are bats in Mississippi dangerous to humans?

What should I do if I find bats in my attic?
Contact a wildlife professional to safely remove and exclude bats from your home, ensuring their safety and yours. Do not attempt to handle them yourself.
Are bats beneficial for the environment?
Yes, bats are vital for controlling insect populations, pollinating plants, and dispersing seeds, making them crucial for healthy ecosystems.
What is white-nose syndrome?
White-nose syndrome is a fungal disease that affects hibernating bats, causing high mortality rates. It has severely impacted bat populations across North America, including Mississippi.
Final Thoughts
Mississippi’s diverse habitats support a wide range of bat species, each playing a unique role in maintaining ecological balance.
