19 New Species of Speedy Praying Mantises Found

A scientist has discovered 19 new species of super-speedy praying mantises that roam Central and South America, a new study says.

The insects belong to a group called bark mantises, which are flatter and broader than the more commonly known mantis.

“They almost look like cockroaches with a narrow front end,” said Gavin Svenson, curator of invertebrate zoology at the Cleveland Museum of Natural History and author of a study published recently in the journal ZooKeys.

Some of the new species have creative names. There’s Liturgusa algorei (above), whose moniker honors former U.S. vice president and environmental activist Al Gore. Liturgusa krattorum is named for Martin and Chris Kratt, the hosts of two popular children’s shows about animals. And Svenson dubbed two of the bark mantises Liturgusa tessae and Liturgusa zoae, after his daughters, Tessa and Zoey. (Also see “Praying Mantis Mimics Flower to Trick Prey.”)

Previously, only ten species of bark mantis were known to science, so the new study nearly triples the known biodiversity of this group.

“This paper will serve as an authoritative work on the bark mantis group for many years to come,” said Jason Cryan, deputy museum director for research and collections at the North Carolina Museum of Natural Sciences in Raleigh, who was not involved in this study.

Speedy, Hidden Hunters

Svenson studied more than 500 bark mantis specimens from museums in North America, South America, and Europe, as well as collected insects from eight countries in Central and South America.

Most bark mantises are highly camouflaged to look like bark or lichen. They spend their lives on tree trunks and branches, where they use their superior vision to hunt smaller insects. (Watch a praying mantis video.)

While most people think of praying mantises as stealthy ambush hunters, Svenson said bark mantises actively pursue their prey and chase it down. “They’re extremely fast,” Svenson says.

Due to their camouflage and speed, bark mantises are not easy to capture. But Svenson figured out a way: He used a long, curved stick to tap the backside of tree trunks.

“Chances are, it will see you coming before you ever notice that it’s there, and it will run to the backside of the tree,” Svenson says. Tapping the back of the tree with the stick makes the mantis run around to the front, where it can be corralled into a net or scooped up by hand.

Svenson also collected bark mantises at night, when he could temporarily stun them by shining a bright spotlight in their eyes.

Unknown Fate

Many of the newly described species are known from only a few specimens collected 50 to 100 years ago, sometimes from places that are now being converted to agricultural uses and urban development.

It’s unknown whether some of the bark mantis species are endangered or even extinct, Svenson said—but he hopes the new study will shed more light on these mysterious animals.

    I had not seen a preying Mantis in nearly 40 years, but saw both a green and a brown in my NY state yard last summer.

    I dont care about insects

    A few days back I saw a what I think was a bark mantis on the mango tree at the back of my grandparents’ house in Dharwad. I was just leaning on a tree when something sped to the other side of the branch. I went and checked and there was this insect. I was wondering which it was when I saw its front limbs folded in that way. It was much flatter than others I had seen.

  • Nandan

    It also camouflaged really well.

    The Kratt brothers have actually hosted 4 shows.

    In Bangalore I saw a dried up twig like creature about an inch long. on a gate. It was almost black and looked like a praying mantis with a difference.It had only a stub in the rear portion instead of the usual large winged stomach like bulk. As I watched it moved towards the end of the gate where there was a gap of about four inches for the other half of the gate. Then it made a few forward and backward swinging motions of its body and jumped the huge gap successfully and went its way. I marveled at its intelligence in estimating the gap and and gathering its attention and strength in the same way as an athlete. I scanned pictures on the net and could find nothing like it.

    I like animals and bugs. I am 10 years old and my mom home schools me. We are having class right now. I had to write paragraphs on all the PBS cartoons I watched this morning. My favorite is Wild Kratts. Will you send me their address so I can write them.

  • Jill Sonntag

    I’ve headed a lot about that an animal has been named after the Kratt brothers and thought it was a joke, but it isn’t and I’m very proud to see it! 🙂 I love their animated show Wild Kratts, it’s one of the best I’ve ever seen in this area.

    This is awesome! Thx for sharing this information with us creature lovers!

    This is a grate discovery

  • Jhon kony

    will you still study and discover more mantis?

  • Jhon kony

    do you know Cris and Martin Kratt ?

  • Jhon kony

    I mean Chris.

    my mom knows someone who was good friends with Chris krattora in high school!
