Are you excited yet?

T-minus 36 hours!!!!!! (give or take a few. And also depending on when you read this.)

Unfortunately (or maybe fortunately...), we're probably going to get to Florida about a month too late to see the "double-headed bugs," or lovebugs (Plecia nearctica), which form huge mating swarms twice a year in late spring and late summer. They can be stuck together for as long as several days during and after mating, even when they're flying around. Their swarms can get so big that they're considered a huge pest, especially when people drive through the swarms. Lovebug body chemistry is not conducive to being cleaned off of car paint (the trick, I have read, is to use wet dryer sheets).

Lovebugs weren't always found in Florida. Actually, because they appeared in the U.S. so suddenly, some brilliant person decided to spread the rumor that the pesty lovebugs were actually the escapees of a genetic experiment gone wrong, accidentally released by naive University of Florida students. However, their sudden introduction to the U.S. can be explained instead by a steady migration around the Gulf of Mexico. Lovebugs were present in Mississippi and Louisiana in 1940, and then expanded their range by about 20 miles per year, until they reached southern Florida in 1975, according to a study by Lawrent Buschman.

The one with the tiny head is the male. Sorry guys. We always knew you had smaller brains.

Unfortunately, these would probably be hard to pin.

One thing you don't have to worry about in Florida: being stung by the bullet ant (Paraponera clavata). The farthest north you'll find the bullet ant is Nicaragua or Honduras, so we've managed to dodge that bullet (so punny).  Apparently the sting of the bullet ant is actually about equal to being shot. This ant is also known as "hormiga veinticuatro" because its sting is followed by 24 hours of pain. It has a 4+ rating on the Schmidt Sting Pain Index (a scale of 1 to 4...yes this is a real scale). Apparently some crazy entomologist from Arizona decided to rate all of the stings of the Hymenoptera by testing them on himself. He didn't just put a numerical rating on the stings, though; he also described them with explicit, almost whimsical phrases. The sting of the sweat bee (family Halictidae) is "light, ephemeral, almost fruity. A tiny spark has singed a single hair on your arm." How enjoyable! Not surprising that it clocks in with a measly rating of 1. The yellow jacket (genuses Vespula and Dolichovespula) packs a heftier blow, with a rated-2 sting that is "hot and smoky, almost irreverent. Imagine WC Fields extinguishing a cigar on your tongue." Ouch. But none come close to our enemy the bullet ant, which causes "pure, intense, brilliant pain. Like fire-walking over flaming charcoal with a 3-inch rusty nail in your heel." I'm not sure what gives this guy the authority to talk about fire-walking with 3-inch (not 2-inch, mind you. This is REAL pain) rusty nails in his heels, but I'm going to trust him. If you want to read more of Schmidt's descriptions, here's a cool article.

Look at the size of that stinger...

On an entirely unrelated note: you know how they always say you know you're fluent in a language when you start dreaming in it? I've never had a dream in another language (we'll ignore the random Spanglish that sometimes crops up), but I have had really cool dreams about bugs. Last night, I caught a really awesome mantis with red wings (why did it have to be a dream?). My kill jar wasn't charged, though, so I had to tell to my brother to pour ethyl acetate into the jar while I was holding the mantis. He poured way too much into the jar, but I couldn't do anything about it because my hands were full of mantis, so I just ended up drowning the thing in ethyl acetate. Rather unfortunate.

I also think I ate some mealy bugs in my dream...yum?

Basically, my point is: SO EXCITED FOR FLORIDA. LET'S CATCH SOME AWESOME STUFF.

Insect Collectors Extraordinare go to the Bronx Zoo!!!

A group of three insect collecting fiends bravely ventured to a land far far away called "the Bronx" this past Saturday. Their quest was to find all the insects and insect-themed attractions the Bronx Zoo had to offer (as well as see all the other really awesome but not as insect-y animals).

                     David "Beard" Kellner              Peter " Creepy" Flynn         Elizabeth "Sorority Squat" Schyling
            

                                                                             Their mug shots


The crew was a little overwhelmed on where to start this insect adventure....

The Bronx Zoo is huge!!

The first place the crew encountered insects was the "jungleworld" exhibit, and ENCOUNTER INSECTS THEY DID! This exhibit focused on animals in the rainforest and since insects account for much of the species diversity in a rainforest this exhibit focused on a variety of insect species. The lighting was dim in jungleworld so there are not pictures from this part of the adventure. Jungleworld had a lot of stick insects, which belong to the Phasmatodea order. One cool example was the huge Eurycantha calcarata  (the thorny devil stick insect), sometimes referred to as the "giant spiny stick insect". This species is endemic to the New Guinean rainforest, and resembles rotten wood. Females are usually about 6 inches long with a large abdomen.

The next stop was the Congo Gorilla Forest! In this exhibit there were many different kinds of beetles for David, Peter, and Elizabeth to gawk at. They got so excited about beetles, since they are by far the most diverse group of insect -- as J.B.S Haldane once said, the Creator must have an "inordinate fondness for beetles!" They took a picture with a beautiful collection of pinned beetles.

Sorority Squatting Next to the Beetle Collection 
Charlie's Angels  Beetle Style (except David didn't get the memo)


Next was possibly the most fun part of the entire trip - the BUG CAROUSEL!!!!!!!! While most of the participants were under age 5, we were not ashamed because we did it in the name of SCIENCE.  Peter scared many of the children with his wild enthusiasm for hexapods.

                    

Peter chose an orthopteran as his steed, while David chose a mantodean, and Elizabeth chose a coleopteran. These matched their personalities well (SPIRIT ANIMALZ).






Question: Is this an arthropod or a chordate?  (Answer - this is a tapir, which is a chordate. Nice try.)

Then the dynamic trio decided to hit up the butterfly garden - a lepidopterist's paradise.  We brought our nets and kill jars, but the zoo staff seemed to frown upon this. The faunal diversity was astounding - there was even a gigantic luna moth.


The resemblance is uncanny.


David examines a butterfly (black swallowtail - Papilio polyxenes ?)



David spent hours to get this perfect shot of a butterfly with a semi-unfurled proboscis (modified mandibles and maxilla, evolved for sucking). Perhaps it had just been sipping nectar from a plant, or perhaps it was about to. The wings are blurry because it flew away just as the photo was taken.

Nice Hat, Elizabeth!

Elizabeth shows she is champion chewer - we knew it! She also uses her expert insect observation as we left the butterfly garden.


The expert adventurers left the Zoo feeling a sense of accomplishment for all that they had done and learned.

THE END!

Real photos of insects in southern Ghana

To follow Kara's blog post, I must say that I totally concur: we should go to Africa.

I spent Summer 2011 in the southern region of Ghana in West Africa. I was there during the raining season, so there were bugs galore. But that was when I had plans for a future in global health. If I had only known I'd be taking this course, I could have had some awesome arthropods to add to my collection. Still, I managed to take some pictures of bugs I had never seen while I was there. Help me identify some of these bugs?

This I know is a tsetse fly. It landed on a fellow NGO researcher's arm. When this happened, a rural Ghanaians slapped his arm really hard! It seemed completely out of nowhere, until we saw the specimen, which landed atop his research notebook.  The tsetse fly is known for causing sleeping sickness in humans. 

Really cool Odonatan. Spotted randomly.

Sweet true bug (? Hemipteran?) I found climbing a wall.

THE COOLEST BUG I SAW. I have not a clue what kind of bug it might be. Some sort of Coleopteran? It's on cement here. I saw quite a lot of them.

Totally a Decapoda. They curled up when they were scared. 

Now, let's go to southern Ghana so I can take you to all the places I spotted these terrestrial arthropods, and we can have some fun times identifying, studying, and collecting them. My contributing thoughts to Yale's presidential search are summed up with one question: who will sponsor exotic weekend trips to Africa for our lab? Not you? How about you? No? Next.

We Should Go to Africa

My dad is currently in Africa doing AIDS research and has been sending me pictures of insects that he sees around.  He hasn't been there for long and has already sent me a bunch of pictures (so clearly the arthropods are everywhere over there). So I think we should to Africa in Thanksgiving break- Marta is always talking about how much money she has to spend, so I'm sure it's feasible.  Look at all the cool stuff we would catch:

African Locust:

Worker Termites coming out of their hill:


Dung Beetle Rolling its Dung:


We'd also get to see other non-arthropod (less cool) organisms like this:







Spider vs Katydid, Who Wins?

My family recently sent me this series of pictures and movie, which caught on film the amazing ability of spiders to catch their prey.  The first picture shows a katydid ignorantly wandering along the window frame to its eventual doom.  The second picture shows how when the katydid tried to take off and fly away, it was ensnared in the massive spider web built in the corner of the window. The video shows the spider's reaction to its prey.  It begins by jumping on top of it. I am fairly certain that it then employs the bite first method, most likely because the katydid is so large and would probably get away if the spider tried to wrap it first.  I think that the spider bit the prey (although you can't see it clearly in the video) because the katydid is slowly subdued and stops struggling.  This huge katydid should keep the spider happy and full for a long time... quite the feast. 

Shout out to my brother for catching this on film for me!

Assortment of Random Arthropod Links 1

This will probably happen more than once on this blog per semester (and hence why I've titled this with "1"). I've been loading up the "Drafts" folder with stuff I've been meaning to post about, but it's gotten out of hand, and I think it would be more productive to post all of the arthropod links at once instead of parsing them all out. So, here's a bunch of stuff I found worthy of a blog post, but didn't necessarily feel were worthy of their own stand-alone posts.

1) http://bugasalt.com/

This website is dedicated to the sale of a salt gun for killing insects within short-range (about 3 feet). The gun prides itself on delivering a dead bug that will still be intact and "easy to clean up" (see FAQ page). Basically, the salt gun uses just a pinch of table salt as its ammunition to aim at unwelcome arthropod guests, especially mosquitoes and flies but also roaches and wasps.

On the order page, you can get this nifty device for a mere $34.95 if you're a lone gunman, or 144 guns for $2,800 (price per gun goes down to $19.44 [yes, I calculated that for you]). Doesn't sound too shabby!

Also, if you're not actually too fond of this device but you still want the thrill of killing flies, go on their website and you'll find a fly flying all over the page, which you can ultimately aim, target, and shoot with the simply click of your mouse.

2) Would you be happy or sad if you found this surprise in your raspberries?
I kind of wish those were my raspberries.

3) Amazing Arthropod Photography by Thomas Shahan 
Desktop background quality "macro" photos of arthropods. This guy takes some fantastic pictures of arthropods in their natural habitats. Definitely take a look--these are amazing.

4) Peacock Spider Gets Down For Love
If only I knew how to mate as well as these peacock spiders, I'd be quite the reproductively successful woman. If you click the link above, you'll find a video of the courtship behavior of this "peacock" spider with a link to a pdf of a preliminary description of the species and an undescribed genus Maratus to which it, as well as another undescribed species from 1931 member to the Peckham collection at the Harvard Museum of Comparative Zoology, belong. Cue Katy Perry's "Peacock"...

5) Fashionable Jumping Spiders
This is a link to a series of macro photographs of jumping spiders that carry a water droplet atop their heads, which reflect the scene around them. My question to you people: real or not real? If you don't think so, I suggest you drop by the photographer's portfolio website and see for yourself.

6) Last, but, DEFINITELY NOT LEAST: Beetles as Jurassic Park People
THIS IS THE MOST IMPORTANT THING YOU WILL EVER CLICK 

AND IF YOU DON'T CLICK IT

JUST LOOK HERE








And.... that's all for now. Have a great weekend, everyone!

Today was the best day ever!

These pictures will tell you why.

1. First, Rich liked my photo submission for a sandwich contest.


2. Then, Val liked my photo submission for a sandwich contest.

3. Then, later, I saw Rich at the gym. A not-so-good part of my day was when he rejected my offer to spot him for bench press. So I decided to put my feelings into action, and...

4. When Rich was doing pull-ups, I snapped a picture of him without him noticing. =]

5. Now, I'm posting this blog entry, and giggles are all around.
