Ohio Bat Species

Bat Week - October 24 - 31, 2017

There are about 45 species of bats in the United States and we have 11of those in Ohio. All Ohio bats
Northern Long-eared Bat
are insectivores which mean they eat insects such as mosquitoes, moths, true bugs and more. One bat can consume over 1000 insects in a night which is a great way to control our insect populations. This also helps our economy because the insect control helps reduce crop destruction. For that reason, farmer's use less pesticides. In the end that means higher crop production at lower production cost which transfers that to the consumer.

A big myth is that bats carry rabies. The truth is less than 1% of bats carry rabies. Just as with any wild animal, we should never go out and pick them up but the chance of getting rabies is slim. Another myth is that bats are blind. The truth is that bats can see but since they move after dark, they use echolocation to find their food. They send out a high frequency sound (too high for humans to hear) and can determine a lot of information from the sounds they emit. This would be object location, size, if it is moving and so much more. A third myth is that they are blood hungry. There are no bats in the U.S. that drink blood. The vampire bats in Central and South America do consume blood but we do not have to worry about that. There are also many myths about them also but since this is on Ohio bats, I will not cover it here.

Meaning Behind Their Names

Bats may have more than one common name as they can vary depending on the geographical location. Scientific names are always written in Latin and italicized. The first is the generic (genus) and the second name is the species. The Latinized scientific names, usually originat from Greek and are descriptive such as physical attributes, habitat, behavior in honor of a person. Some of the genus meanings in Ohio are:

Corynorhinus—from the Greek coryn, meaning “club,” and rhinos, meaning “nose.”
        rafinesquii—patronym for Constantine S. Rafinesque, an early American naturalist.
Eptesicus—Latin for “house flier.”  Big brown bats often live in houses.
        fuscus—Latin for “brown.”
Lasionycteris—from two Greek words, lasios, meaning “hairy,” and nycteris, meaning “bat.”
        noctivagans—from the Latin nox, meaning “night,” and vagans, meaning “wanderer.”
Lasiurus—from the Greek lasios, meaning “hairy,” and oura, meaning “tail,” a reference to the heavily furred uropatagium.
        borealis—Latin for “northern.”
        cinereus—Latin for “ashen” or “gray.”
        intermedius—Latin for “intermediate.”
        seminolus—refers to the Seminole Indians, who lived in the region where the type specimen was obtained.
Myotis—from the Greek words mys, meaning “mouse,” and otus, meaning “ear.”
        austroriparius—from two Latin words, austro, meaning “southern,” and riparius, which means “frequenting the banks of streams.”
        grisescens—from the Latin word griseus, meaning “becoming gray.”
        leibii—a patronym recognizing George Leib, collector of the type specimen.
        lucifugus—Latin for “to flee from light.”
        septentrionalis—Latin for “northern.”
        sodalis—Latin for “companion,” referring to the habit of hibernating in large numbers.
Nycticeus—Latin for “belonging to the night.”
        humeralis—Latin for “of the forelimb.”
Perimyotis—from the Greek word peri, meaning “about” or “around,” referring to the fact that this bat is closely related to the genus Myotis.

Final "Stream Quality Monitoring" of the Season

I am sad to see the sampling season come to a close. This was my first year of sampling the
macroinvertebrates and I learned a lot. Not only did I learn to identify some of the bugs but I learned about some of the life stages and habitats. I have a better understanding of a stream habitat such as substrate, water, vegetation, riparian zone and so much more. Learning these different sections of a habitat has provided me with a greater understanding of how the macroinvertebrates rely on the complete system and how the system helps (or destroys) the macroinvertebrates.

Winter will soon be here and I love winter. I am not one who hibernates when it gets cold. I actually love getting out and taking winter hikes. It is now time to change direction and work on other projects. I will brush up on my macroinvertebrate identification and work on finding a good bat roost for next spring as I am also monitoring bats. I will also find tasks that I can do for ODNR and FLOW for the winter months. Plus MAD Scientist has also been added to my volunteer activities. Check out the "video" tab and "gallery" tab above to see some of my finds for the summer.

As I said above, it is just changing gears for the winter months, The way I see it, outdoors is always open and nature is always moving. I plan to go out and check out the activities taking place at some of streams. Many animals are still out living life and hunting for food.

The sampling season went out with a bang because I found some macroinvertebrates that I have not seen all summer such as a large aquatic worm (4"), a horsefly larva (1.5") and a surplus of stonefly nymphs. So I am glad that my final sampling gave me some awesome finds.

If you look at the video, you will see that the water is moving pretty fast. I actually had to brace the net against myself when I first put it in the water as the water pushed back on the net.



I set up my work area on this small island in the river. Usually this area is under water. On the left I did two samples and it was about 12-18" deep in the riffles though there was a pool about 24" deep. The left side was also faster moving and is the area in above video. I did one sample on right side that was about 8" deep and slower moving water.

Bat Week - October 24 - 31, 2017


Bat Week is coming up and is the time to learn more about bats and their importance. One bat can consume over 1000 insects in one night, they help control insect populations that destroy farmer's crops and they pollinate numerous plants and flowers - some which rely 100% on bats.

This is also a time to hold your own bat party, dress up like a bat for Halloween and so much more.
