About Erin M

As an entomologist at the Cockrell Butterfly Center, Erin designs, creates, and maintains exhibits for the Entomology Hall, raises and cares for live insects and insect relatives, and educates the public about the wonderful world of bugs.

What has eight legs and is coming to a school near you? “Awesome Arachnids” from HMNS!

In 2015, The Cockrell Butterfly Center will be making a couple of new outreach programs available to classrooms all over the Houston area. One of which was given to kindergarten students at St. Francis Episcopal School in December, and it was a hit, Awesome Arachnids!

For almost 10 years, we have been fascinating kids with “Amazing Arthropods”, a program that introduces students to members of the major classes of arthropods, mostly insects. We always include a tarantula to represent arachnids and can get quite carried away with talking about them. Unfortunately, we are only afforded about 5 minutes per presentation to do this. This frustrated me, as arachnids are one of the most feared and misunderstood classes of arthropods, but they are also SO COOL! So, the idea of Awesome Arachnids was born!

In this presentation, Entomologists from the Cockrell Butterfly Center will introduce you to some of our most interesting eight-legged creatures and explain the features that make them different from their six-legged cousins and other relatives.

Have you ever wondered what a tarantula feels like? Have you ever seen a scorpion change color right before your eyes? Can you even name any other types of arachnids? Don’t worry, that’s what we’re here for!

Here is a sneak peek at some of the stars of our show…

Ed Bugs 1

Rosie, a Chilean Rose Hair Tarantula, is one of two terrific tarantulas you can meet during the Awesome Arachnids program!

Rosie and Peanut, 20 and 10 years old, respectively, are two of our special tarantula ambassadors! They will help ease you into the world of spiders – one of the most feared types of animals on the planet. As many as 55% of females and 18% of males in Western society are estimated to have arachnophobia – a fear of spiders and other arachnids. Although spiders are venomous, and venom CAN cause people harm, more often than not, a spider is harmless to us. No one helps illustrate that point better than Peanut and Rosie, with their furry appearance and docile nature. We will teach you all about spiders; which ones are ok, which ones to avoid, and how they help us way more than they could ever harm us.

Ed Bugs 3

Vinny the Vinegaroon may look scary, but he’s really a shy guy with a very unique defense mechanism!

Vinny is a bizarre looking creature, one that most people have never come across before! Vinegaroons, also known as whip scorpions, inhabit tropical and sub-tropical areas all over the world. They have no venom glands, so cannot bite or sting. They are very shy, spending most of their time underneath rotten logs or rocks. At night, they hunt for insects, worms, and slugs. They help us control cockroach and cricket populations. Why are they called vinegaroons? Well, you’ll have to meet Vinny to find out. Once you meet him, you’ll want to meet more bizarre looking creatures like him!

Pinchy the Emperor Scorpion is one of the largest scorpions in the world!

Scorpions are another arachnid that most people fear, and for good reason! That intimidating looking stinger can pack quite a punch! Fortunately, the venom in their sting is formulated to act on other invertebrates, so it is USUALLY not dangerous to us, but can be quite painful! Emperor scorpions, like Pinchy, have very mild venom, no more severe than a bee sting. They are also more likely to pinch with their large, strong claws than sting, hence the name! Scorpions are incredible animals and have many characteristics that set them apart from other arachnids. Want to know more? We’ll be happy to share with you!

Children will be allowed to gently pet arachnids which pose no threat to their safety, such as the tarantulas. Necessary precautions are taken by the presenters to ensure the safety of the children and the animals at all times.

So there you have it! Hopefully we’ve whet your appetite for more fun facts and stories about these fantastic creepy crawlies! If you’re interested in bringing Awesome Arachnids to your school – just email us at outreach@hmns.org, or give us a call at 713-639-4758!

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.

toadally memeWe have several arthropods and even some reptiles and amphibians that we will showcase. Here is a little about the line-up for this Friday (note: it changes weekly).

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!
