Meet the live animals that’ll be starring in this week’s Friday Feeding Frenzy

Get ready to see huge, ferocious, carnivorous insects and other animals feast on their prey in front of your very own eyes!

Every Friday throughout the summer, the Cockrell Butterfly Center will be hosting the Friday Feeding Frenzy, where we will be feeding live animals for your viewing pleasure at 9:30 a.m., 10 a.m., 10:30 a.m., and 11:30 a.m.. The cost is included with admission to the Butterfly Center.

GREEN TREE PYTHON 
Morelia viridis

Our green tree pythons, Boo and Hiss, will be ready to dine on mice! These snakes are native to Indonesia, Australia, and New Guinea. Pythons are non-venomous snakes that subdue their prey by constricting. Their food consists mostly of small mammals and the occasional reptile. They lay in wait, curled around a tree branch. When potential prey approaches, they strike from an “S” position, using their tail as an anchor to the branch. Once their prey is snagged, it’s lights out!

 

GIANT ASIAN MANTIS
Hierodula membranacea

Feeding Frenzy 4This praying mantis, one of the largest species, comes from Southeast Asia. Mantises are ambush predators and have several features that ensure their success in catching prey.

Due to their amazing camouflage, praying mantises can resemble either living or dead parts of plants, flowers, tree bark, stones, or sticks. Not only does this help conceal them from predators, but it keeps potential prey oblivious to their presence.

An insect that wanders too close is quickly snagged by raptorial front legs (read: legs specialized for grabbing) and held still by several tough spines. The mantis uses chewing mandibles to eat its victim alive.

Mantises have excellent vision at close range and can see as far as 20 meters. Their eyes are large and located on the sides of their heads, allowing the insect to see all around them. They can keep their eyes on potential prey by inconspicuously moving their heads up to 180 degrees. Nothing can escape their field of vision.

Most mantises feed on smaller insects, but some giant species can take down small reptiles, amphibians, and even rodents.

 

GIANT CENTIPEDE
Scolopendra heros

Feeding Frenzy 8Centipedes are predatory, long-bodied arthropods with many pairs of legs — 1 pair per body segment. Centipedes are venomous and can be dangerous, so they are not to be confused with the congenial millipede, which poses no threat to humans and has four legs per body segment.

This centipede, also known as the giant red-headed centipede, can run very quickly to pursue prey. Once caught, the prey is bitten repeatedly by two fangs, which inject venom to immobilize and kill. Then the meal is devoured!

Giant centipedes of this and other similar species are found in Mexico and the southwestern United States. The coloration, known as aposematic or warning coloration, serves as a message to other animals: “Touch me and you’ll get more than you bargained for!”

A bite from one of these can cause intense pain that lasts for hours or days and can cause a severe reaction in someone who is allergic. These hunters take down smaller arthropods, small reptiles and amphibians, small rodents, and have even been known to hunt tarantulas.

 

WOLF SPIDER
Hogna carolinensis

Feeding Frenzy 6This is the largest species of wolf spider found in the United States. Most wolf spiders are large and can sometimes be confused with tarantulas.

The name “wolf spider” refers to their hunting behavior. They don’t build a web designed to ensnare prey, but actively seek out their prey. Sometimes they wait to ambush their prey and at other times they chase it for a short distance.

Wolf spiders inject venom into their prey to immobilize it. They then use digestive enzymes to liquify the insides and then slurp it up through a tube that leads to the stomach.

Wolf spiders have no interest in biting people, but will if provoked. The severity of their bite has been compared to that of a bee sting.

 

GOLIATH BIRDEATER TARANTULA
Theraphosa blondi

Feeding Frenzy 7This is the big momma of all tarantulas and regarded as the largest spider in the world. They can reach a weight of 5.3 ounces (more than a Quarter Pounder) and have a leg span of 12 inches (about the size of a dinner plate!). The name “birdeater” is a misnomer as they do not eat birds, although they could.

They are native to marshy swamplands in South America, and like other large spiders, they feed on mostly insects. However, because of their size, they often go for small reptiles, amphibians, and rodents.

If threatened, these tarantulas can produce an eerie hissing noise by rubbing together setae on their legs. If that doesn’t creep you out enough to stay away, watch out for the urticating hairs that are kicked off of the abdomen into air. If these hairs come into contact with the skin, you get really itchy. And you don’t even want to know what happens if it gets in your eyes!

Birdie is our resident birdeater and she’s a thrill to watch as she shoves as many crickets into her mouth as possible.

 

GULF COAST TOAD
Incilius valliceps

Feeding Frenzy 3You see those toads everywhere around here — unfortunately, often they are smushed by cars in the street.

Well, these guys aren’t getting run over. They get a five-star aquarium and an all-you-can-eat buffet provide by the Butterfly Center! Toads are opportunistic predators and will eat any small animal they can fit into their mouths, so they should be fun to watch.

 

AFRICAN BULLFROG
Pyxicephalus adspersus

Feeding Frenzy 5Last but not least, meet Tofu! Tofu is staying with us while his owner, a friend of the Butterfly Center, is in Australia. We promised to take good care of him and feed him well, for all of you to see.

African bullfrogs are huge and the males can reach 10 inches. Like other frogs and toads, they are voracious predators and will eat anything they can fit in their mouths, including small rodents and birds.

African bullfrogs can spontaneously change genders in a single-sex environment — how’s that for a neat trick? Remember how, in Jurassic Park, the dinosaurs were all female, so they weren’t supposed to be able to breed? And remember what happened after frog DNA was added to the dinosaur DNA? Just like African bullfrogs, the Jurassic Park dinosaurs were able to switch their genders and breed, because as they say, “Life will find a way.” Silly humans!

We’re all pretty enamored with Tofu around here, so we can’t wait for you to meet him.

Well, there you have it folks, the Friday Feeding Frenzy line-up! Not only will you get up close and personal with these live animals, but you will also learn some cool facts and be able to ask questions.

While you’re in the Butterfly Center, don’t forget to check out 25 more amazing insects and other arthropods on display, and more than 1,000 free-flying butterflies. See you Friday!

So tiny I almost couldn’t focus

One of my favorite parts of this job is raising baby insects. It may not be like raising a baby, or even a cat or dog, (sometimes you have to feed them living things) but it is still very fun and rewarding. Plus, baby insects are really cute as you’ve seen from my previous posts. This week, the stork brought us about 100 Giant Asian Mantis nymphs. They are so cute.

Giant Asian Mantids (Hierodula membranacea) are a species of very large, impressive mantids from Southeast Asia. They are typical-looking and resemble some of our native mantis species, but are much larger. They come in a wide range of beautiful colors, such as bright green, yellow, orange, grey, pale peach, or brown.

They are quite voracious and will go after a wide variety of prey.  The adults are of one of the few species that will even eat a pinky mouse (shudder). Mantids are known as ambush predators. This is why they have camouflage coloration, which helps them hide from their predators and prey. They are not equipped for running after prey, so they have to be able to lunge and grab things very quickly. Their characteristic “praying” front legs are equipped with lines of teeth or spines to grab and hold on to squirming animals and they are very strong. Mantids also have excellent vision.  Predators in the insect world need to have accute vision to be able to see potential prey moving and flying around them.

Violet is the proud mother of these babies. She is a gorgeous specimen, bright peach colored with light violet eyes (hence the name). She is the first mantis we’ve been able to take out for Bugs on Wheels. While others may freak out and jump, fly away, or bite your hand thinking it’s a really fat cricket, Violet just climbs up and looks around curiously. It’s like she trusts us, or, just knows that we take care of her and provide her with food. We will be so sad to see her go some day, but I feel great knowing I’m raising her babies and hopefully one of them will be as special as she is.

Raising baby mantids is really fun and easy, and it can be a great science experiment for home or the classroom. Mantis egg cases are available for purchase from a few web sites, like Insect Lore and Carolina Biological Supply, or some garden centers and nurseries. You can release most of the babies into your garden and keep the rest to raise yourself.

Once the babies hatch, they can be fed flightless fruit flies which are available from Fluker Farms.  They should be kept in a container with a mesh lid and plenty of small sticks and twigs. They need to have several places to hang from so they can molt. They should be fed fruit flies at least 3 times a week and sprayed with a fine mist of water a couple of times a week.

Once they get bigger, you can move on to feeding them small crickets, then bigger crickets and so on. If you have several, be sure to separate them as they get bigger, so they won’t eat each other. When they have made it to adulthood, you can release them into the wild, so they can start the cycle over again. 

Watching insects complete their life-cycle is really an amazing experience and it can teach you so much – maybe even mom and dad will learn something. I will leave you with this video of Violet’s green sister catching her meal. Happy bug watching.
