If you take the time to watch the dragonflies, you’ll quickly notice they are amazing critters.
How much do you really know about dragonflies though?
Here are some little-known facts from our new book, The Secret Lives of Animals, due out October 1st.
- True of false? Girl dragonflies are called damselflies? False! The damselfly is actually a completely different type of insect. The easiest way to tell them apart from dragonflies is that damselflies tend to rest with their wings folded behind their bodies, while dragonflies rest with theirs held out to the sides.
- Dragonflies fossils date back more than 300 million years. In fact, some prehistoric dragonflies had wingspans of 2 feet. Imagine that flying around!
- The larval stage of dragonflies survive underwater for up to two years, so you might not recognize them as dragonflies.
- Dragonflies are amazing fliers and hunters. In fact, they combine the two really well, because they do all of their hunting while flying.
- An adult dragonfly might live from just a couple of weeks to about a year.
- Adult dragonflies can eat one hundred or more mosquitoes a day, so next time you see a dragonfly be sure to thank it.
- Dragonflies have amazing vision. Their two compound eyes can practically see 360 degrees.
- A few dragonflies, like green darners, will migrate each year. Have you seen any dragonflies migrating this fall?
