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the most indicative factor in differentiating between megabats and microbats, “Microchiroptera” suborder is considered outdated.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.

Top 3 Traits of a Microbat

Posted on February 17, 2020 by virginia

Bats are mammals that are a part of the Chiroptera order. The word “Chiroptera” is derived from the Greek word “hand-wing” in reference to a bat’s webbed hand-like wings. Chiroptera is the scientific classification of bats. There are thousands of bat species all over the world, but all species can fall under one of two main categories, Microchiroptera and Megachiroptera; colloquially referred to as microbats and megabats. Although recent evidence more so supports the division of bat species into Yinpterochiroptera and Yangochiroptera, it is still very common to use the terms microbat and megabat.

But since we don’t see any megabats in Virginia, continue reading to learn the top 3 traits of a microbat!

Virginian Bat Species

Here in Virginia, we have microbat populations. Three species of bat in Virginia are Federally-endangered, and include the Gray Bat (Myotis grisescens), Indiana Bat (Myotis sodalist), and the Virginia Big-Eared Bat (Corynorhinus townsendii virginianus). In addition, there are 12 non-game protected species of bat found in Virginia, including the Eastern Small-footed Bat, Northern Long-eared Bat, Eastern Pipistrelle Bat, Silver-haired Bat, Eastern Red Bat, Hoary Bat, Seminole Bat, American Long-Eared Bat, Lump-Nosed Bat, Ozark Big-Eared Bat, Townsend’s Big-Eared Bat, and the Northern Myotis.

Although there are 15 species of microbat in our state, each species exhibits common microbat traits. The top three traits are ones that all microbat share, regardless of species: small, omnivorous, and echolocating.

? Small

Microbats are not called micro because they are big! Microbats are small in stature and size, which is why they are so good at finding places to roost. The average microbat can fit through an opening or crack as small as 3/8^th of an inch. That is equivalent to the thickness of a pencil eraser! Take the Virginia Big-Eared Bat for example; although it is one of the largest Microchiroptera species in its range, it still only weighs an average of 7 to 12 grams (0.25 to 0.42 ounces).

? Insectivorous

Microbats are insectivores, which means they strictly eat bugs. They mostly dine on flying ones, like mosquitoes, flies, gnats, moths, wasps, and bees. They also will consume termites, dragonflies, grasshoppers, and beetles. A single bat can consume more than its own body weight in insects, in just one single evening. That’s an average of 1,000 insects or more.

? Echolocating

Microbats use echolocation, much like dolphins and whales. Echolocation is a natural biological sonar ability that works by measuring the returning echoes of emitted signals that bounce off surrounding objects. Bats are not blind, but they use echolocation because it gives them a superior advantage when it comes to hunting and diving for prey at night.

The Differences Between Megabats and Microbats

Posted on January 5, 2018 by virginia

There are two primary suborders that all bats can be categorized in depending on their particular biologics and physiognomies. These suborders are Microchiroptera and Megachiroptera. Continue reading to learn about them both, and the attributes that set them apart.

Megachiroptera – Fruit Bat

Classification of Bats

Bats are part of the Animal Kingdom, and further broken down into narrower classifications, including the Chordata Phylum, Mammalia Class, and of course, the Chiroptera Order. Within the Chirptera Order, bats are categorized into one of two suborders: Microchiroptera and Megachiroptera. Also referred to as microbats and megabats, these suborders are quite different in size, diet, habitat, and more.

Microchiroptera – Microbats

Microchiroptera bats are small, echolocating bats that maintain an insectivorous diet, with the exception of Vampire Bat species, which retain a dietary trait called hemotophagy, and consumes small droplets of blood on livestock like cows, horses, sheep, and goats. Other than Vampire Bats, microbats primarily eat a wide variety of insects, including moths, flies, mosquitos, grasshoppers, dragonflies, crickets, beetles, termites, ants, and more. It is rare, but some larger species of microbat hunt birds, lizards, frogs, smaller bats, or even fish. They generally roost in trees, caves, abandoned mines, and buildings in forested or wooded areas that are near bodies of water. Microbats make up the nuisance bat populations in our area of the country, with 9 species of bat native to Virginia.

Microchiroptera Bat

In appearance, microbats are much smaller than megabats. They have much smaller bodies and smaller eyes, but they are not blind. They can see quite well, and use their echolocating abilities to better dive and dart for prey. Microbats also lack the claw at the second finger of the forelimb. As for ears, microbats have larger ears that retain a tragus, which is thought to aid in echolocation. Megabats have small ears and no tragus, but large visual cortexes that allow them to see well.

Megachiroptera – Megabats

Megachiroptera bats only includes one family, Pteropodidae, but can be further narrowed into 7 Subfamilies, including Nyctimeninae, Cynopterinae, Harpiyonycterinae, Macroglossinae, Pteropodinae, Rousettinae, and Epomophorinae, and 166 different species. Also known as megabats, old world fruit bats, and simply, fruit bats, Megachiroptera is a significantly different suborder of bats compared to Microchiroptera. They are much larger in size, and live in tropical and subtropical climates. The most significant difference is that they do not possess echolocation abilities, nor do they eat insects.

Instead, megabats have large eyes and have great vision. Furthermore, they maintain nectarivores and frugivorous diets that primarily consist of plant material, such as fruit, nectar, or pollen. Megabats make their homes in trees, shrubs, and sometimes caves located near edges of water. They play an integral role in the surrounding ecosystem because they help to spread seeds and pollen through feeding and elimination.
