Nature’s Real Vampires
Halloween is just around the corner and you may soon have “vampires” knocking at your door looking for a sweet treat. In your classroom, this is the perfect time of year to introduce your students to some of nature’s real vampires.
Vampires are animals that consume blood as their food. Below are six of nature’s “blood suckers.” Have you seen any of them?
- Vampire Bat—This is the only mammal that feeds entirely on blood.
- Mosquito—Only the females drink blood, using the protein and iron from the liquid to make their eggs.
- Assassin Bug—It injects saliva, containing anti-coagulants, while it sucks up blood.
- Leeches—Humans have long (and sometimes misguidedly) depended on leeches for medical purposes.
- Bedbug—They disappear during the day (usually into bedding and furniture) and emerge at night to feed.
- Tick—These are among the most-feared vampires because they transmit illness, such as Lyme disease, Colorado tick fever, and Rocky Mountain spotted fever.
- Fleas—All of the world’s 2,000-plus flea species subsist on mammal blood.

INSIDE: Into the Bat Cave
Of the world’s more than 1,000 bat species, only three drink blood. These bats are native to South America, Central America, and two Caribbean islands. Most bats eat insects or fruit. These amazing mammals have long been misunderstood! Begin your science study just in time for the Halloween season by immersing students in learning about bats.
- Scholastic describes seven easy and interesting science activities.
- A source of good bat information is from the Lava Bed National Monument. I’m so glad the government is up and running again so I can link to this good government website.
OUTSIDE: Bat and Moth
Many bats use echolocation to find their food. Simulate echolocation by playing a game that involves your entire class. Download complete directions for playing the Bat and Moth Game. Note: It may also be played indoors as long as you have a space large enough to make a circle with all of your students.
