What is a Microbat?

Posted on September 13, 2022 by virginia

In a previous blog, we discussed that all bat species are classified as one of two suborders, either Megachiroptera or Microchiroptera. In Virginia, we do not see megabats since they are biologically acclimated to tropical and subtropical climates. When local property owners are dealing with nuisance bat problems around here, it is always a Microchiroptera species to blame.

Continue reading to learn more about Megachiroptera suborder, and the common species native to the surrounding Virginia areas.

Yangochiroptera is the New Microchiroptera

Until recently, Microchiroptera was the suborder that included all microbat species. However, after new molecular evidence proved that size is not the most indicative factor in differentiating between megabats and microbats, “Microchiroptera” suborder is considered outdated. Most previously classified “microbats” are now classified as Yangochiroptera, with the exception of a few species. Furthermore, this evidence has also merged a few microbat species into the Yinpterochiroptera suborder, along with fruit bats, flying foxes, and other megabat species.

Special Note: For the sake of avoiding confusion, we will stick with the conversational terms, “microbats” or “Microchiroptera” in this blog.

Echolocation

One of the most significant differences between megabats and microbats is the use of echolocation. Megabats do not use echolocation, while virtually all microbats do. Echolocation, also known as “bio sonar”, is essentially a built-in sonar system that allows bats to navigate their surroundings more precisely, which aids in detecting, darting, and diving for insects.

Echolocation works by emitting ultrasonic sounds that bounce off objects and return as echoes. Bats then compare the outgoing ultrasonic pulses with the incoming echoes to create a detailed image in their brain of their exact surroundings.

Many people wrongly assume that bats are blind and have to use echolocation in order to see, when the truth is, bats see quite well, and simply rely on bio sonar for enhanced hunting and navigating. Sunglasses are a good example. We don’t need them to see when it’s sunny out, but when we wear them, we can see a lot better.

Diet and Habitat

Microbats are insectivores, which is actually good news for us. They are terrific pest control for summer mosquitos, flies, gnats, and more. Some species are even known to consume small fish, amphibians, birds, and even the blood of livestock. Although microbats are vital to our surrounding ecosystem and environment, they can sometimes find their way into our homes and businesses and create quite the mess. When microbats are not roosting (a species-specific posture of hanging upside down by their feet) in attics, crawl spaces, garages, walls, roofs, and more, they generally take shelter in hollowed trees, caves, log piles, and abandoned mines.

Behavior and Reproduction

Most bats are colonial, meaning they live in large colonies. They are not generally solitary mammals, although some species do live alone or with just a few other bats. It is common for colonies to have hundreds, or even thousands, of bats. Studies have shown that they are capable of forming and maintaining long-term relationships, and that many species use food sharing and mutual grooming to strengthen social bonds.

Late summer and early fall are the typical mating seasons for most species. After females finish mating, they store the male’s sperm until the following spring when they emerge from their hibernacula to find a new summer home where they will establish a nesting area to give birth to their young. These are referred to as “maternity” or “nursing” colonies. Bat babies, called “pups”, are usually born in May or June. Gestation periods last between 40 days and 60 days, and females usually give birth to just one or two pups that remain with them until the fall when the cycle of mating and hibernation repeats itself.

Can Bats See Without Using Echolocation?

Posted on July 21, 2022 by virginia

Have you ever used the adage, “blind as a bat?” If so, you may be disappointed to learn that you were incorrect. That is because bats are not actually blind. But don’t be ashamed if you always thought this; many people share the same misconception. The truth is that there are more than 1,100 bat species in the world, and not one of those species is blind. What’s even more interesting is that they actually have quite good vision, especially Megachiroptera species (fruit and old-world). This makes sense, as they are night-hunters. So, vision is important for darting and dashing for prey.

Not All Bats Have Echolocating Abilities

There are two main categories of bat species: Megachiroptera and Microchiroptera (also known as megabats and microbats). One of these bat groups have echolocating abilities, while the others do not.

Megachiroptera Bat Species

Megachiroptera are large bats that live in tropical and subtropical climates. They maintain a diet of fruits and nectar, but some species are also known to consume small amphibians and fish. As for vision, Megachiroptera have large eyes and pronounced visual cortex that allow them to see very well. They also have a good sense of smell. Some species, like Flying Foxes, actually see well during the day, and are dependent on their daytime vision to fly around on moonless nights. They can also see in color!

Microchiroptera Bats

Microchiroptera, or microbats, are different from Megabats in many ways; however, their vision is just as good. Despite their poorly developed small eyes, scientists have confirmed that microbats have both rods and cone photoreceptor cells in the retinas, giving them the ability to see in the day, in color, and at night. Furthermore, Microchiroptera (not all species, but most) have a built-in sonar system called echolocation, which emits high-frequency ultrasonic pulses into the air that bounce back and outline the surrounding environment. This is why many people believe these mammals are blind; but echolocation is simply a bonus attribute that allows microbats to hunt faster and better for insects like mosquitos, moths, flies, gnats, and more.

Nuisance Bat Problems

If you are experiencing nuisance bat problems in or around your property, you have safe and affordable options. Never attempt to catch, trap, touch, harm, or kill a bat. Not only are there possible laws against this, which could subject you to some hefty fines and other civil penalties, but bats also carry diseases, some of which are deadly. Always contact a licensed and insured bat removal and control company in Richmon d , VA for non-lethal, licensed assistance you can trust.

Facts About Megabats and Microbats

Posted on April 5, 2021 by virginia

Did you know there are two main species of bats in the world? It’s true! All bats can be put into one of two categories: Microchiroptera or Megachiroptera. These are colloquially known as “megabats” and “microbats.” Continue reading to learn the main differences and distinctions between them, including their appearance, diet, habitat, and more!

Microchiroptera Vs. Megachiroptera Bats

Microbats

The above image are two Brown Long-Eared Bats, which is a type of microbat species. Microchiroptera, or microbats, are small in size and have large ears. Most range between 3 and 16 inches in length, and many are small enough to fit through a gap as tiny as 3/8^th of an inch. They are echolocating mammals, meaning they use a built-in, biological sonar system, which emits ultrasonic sounds that bounce of nearby objects and return to the bat. Micros are not blind, but echolocation helps them dart and dive for prey more accurately at night.

As for diet, micros primarily eat insects; but some larger species eat small fish, rodents, birds, and amphibians. Three particular species consumes the blood of other animals, mainly livestock and birds. These include Common Vampire bats (Desmodus rotundus), hairy-legged vampire bats (Diphylla ecaudata), and white-winged vampire bats. But do not worry; they do not drink human blood!

When it comes to habitat, microbats live in moderate climates, and typically roost in hollowed trees, abandoned mines, caves, and even in residential and commercial buildings (especially attics!).

Megabats

The Gray-Headed Flying Fox Bat is a Megabat!

Megachiroptera are much larger in size, and are also known as “Flying Foxes”, “Fruit Bats”, and “Old World Fruit Bats.” This is mainly due to their frugivorous and nectarivorous diets, which mainly consists of fruit, nectar, and pollen. Some species are known to eat some insects, but their diet primarily consists of the nectar and pollen of fruit and flowers. Because of this, this suborder of bats do not use nor retain echolocating abilities. They do, however, have a keen sense of smell that helps them locate food sources, as well as, adapted teeth that are strong enough to bite through fruit rinds.

As for appearance, it is easy to differentiate a mega from a micro. Not only do fruit bats have large eyes and visual cortexes, they also lack a tail. However, Microbats lack the claw at the second finger of the forelimb that megabats do have. Megabats live in hot, tropical, and subtropical regions of the world. You are not likely to see wild fruit bats living in the forests of the U.S. Midwest. They prefer hot, humid, damp environments, such as rain forests and shorelines, and they generally make their roost in trees, shrubs, and caves.

The Difference Between the Big Brown Bat and Little Brown Bat

Posted on March 24, 2020 by virginia

Although they may look a lot alike, and they are both part of the Vespertilionidae family, the Big Brown bat and the Little Brown bat are two completely separate species in a different genus. When you scroll down the scientific classification of both species, they have the same Kingdom (Animalia), Phylum (Chordata), Class (Mammalia), Order (Chiroptera), and even Family (Vespertilionidae). But once you reach the genus, they separate.

Virginia Bat Removal and Control 804-729-9097 — Big Brown Bat (Eptesicus fuscus)

The Big Brown Bat (Eptesicus fuscus)

The Big Brown bat (Eptesicus fuscus) is part of the Eptesicus genus and fucus species. Adults have an average wingspan of 13 to 16 inches, and a body length of 3 1/2 to 5 1/2 inches. They are a little bigger as you can see! The rest of their biology and behaviors are the same, with just slight differences.

Their fur is the same as Little Brown bats, ranging in colors from dark browns to reddish hues and lighter-colored bellies. Gestation periods and breeding are the same for both species, as well. Females carry their young for 60 days, before giving birth to a single bat pup each year.

Mating season usually begins in early fall, while birthing season starts in May and continues through June. After 14 days in their mother’s care, bat pups are weaned from milk and taught to fly and hunt for insects. In contrast to Little Brown bats, Big Brown bats tend to roost in smaller colonies, ranging from as little as 20 bats, up to 500 or more.

The Little Brown Bat (Myotis lucifugus)

Little Brown bats are part of the Myotis genus and lucifugus species. Adults have an average wingspan of 9 to 11 inches, and a body length of 2 1/2 to 4 inches. They are small! Their fur ranges in colors of dark browns to reddish browns, with lighter-colored, pale tan bellies. Females carry their young for 60 days, before giving birth to a single bat pup each year.

Mating season usually begins in early fall, while birthing season starts in May and continues through July. After 14 days in their mother’s care, bat pups are weaned from milk and taught to fly and hunt for insects. Little Brown bats, like all bats, are nocturnal, which means they are active from dusk until dawn. Generally, this bat species remains in large numbers, with colonies reaching hundreds or even thousands of bats in some regions.

Typically, Little Brown bats roost in hollowed tree cavities, abandoned mines, caves, log piles, and similar private areas. They are a hibernating species, so in winter, they either migrate to winter roosts, or hibernate in caves, rock crevices, storm sewers, and if they can access them, our attics! As insectivores, Little Brown bats hunt for mosquitoes, gnats, moths, crane flies, beetles, mayflies, and other small flying insects. A single bat can consume more than 1,000 flying bugs in just one night!
