Episode 55 – Dracula Ant: The Formidable Formica

“…and today we’re talking about an ant that can’t grant kindness when food is scant. Even aunt ants pant for a hemolymph transplant. But more on that later.”

Madagascar is a place that’s been isolated by ocean for as long as it has existed, and it’s only recently started to be developed by humans. Because of this isolation, animals here haven’t needed to adapt to new threats, so they still cling to ancient methods, like a small town library that still uses dial-up. A closer look at the creatures here will reveal some primordial practices that may make some squeamish, like an entire family of ants that has sinister tastes in cuisine. But sometimes, the gruesome and grisly tactics are what it takes for your colony to continue in the cycle of Life, Death, and Taxonomy.

Measure Up

Worker Length – 3.5 to 4.5  mm – 4 mm – How many ant’s go into the height of the Monument to Party Founding in North Korea(160 ft)? Hint: The monument was dedicated to the Workers Party of Korea and displays a hammer, sickle and calligraphy brush symbolize the workers, farmers and intellectuals, which is typical communist symbology and the cornerstone of North Korea’s communist propaganda. Answer: 12,192 ants

Colony size – 10,000 workers – How many Roanoke Colonies (116) go into a Dracula ant colony? Hint: The colony at Roanoke was established in 1585 on an colonizing expedition lead by john white. They fell on hard times and White sailed to England for supplies and help, but he was unable to return for three years. When he returned in 1590, the colonists were gone, and we still don’t know what happened to them to this day.  Answer: 86 colonies

Fast Fact

  • Mystrium Camillae is a species of Dracula ant that is the fast animal on the planet, but not in terms of how fast they run.
  • They snap their mandibles at a speed from 0 to 200 mph in 0.000015 seconds, 1,000 times faster than you can snap your fingers.
  • Researches say this is the fastest animal movement ever recorded.
  • They don’t snap them from open to shut though.
  • They start with the tips of each mandible touching and the squeeze them together, causing them to bow with potential energy.
  • Then they snap them, on sliding over the other.
  • The force of the snap can break or stun anything that touches it.
  • Except solid objects like a researcher’s forceps, in which case the forces sends the ant spinning violently away.

Major Fact

  • Most ants engage in social food behavior.
    • They will forage for food sources, like crumbs on your kitchen counter, and carry them back to the nest where they will share with each other and the queen.
  • However, adult Dracula ant’s can’t consume and digest solid foods.
  • But their larvae can. Sort of like the opposite of humans.
  • They feed the larvae, giving them all the nutrients they need, but for a gruesome price.
  • The adult ants tending to the nursery will make a small incision in the larvae’s body, and then they drink their blood.
  • The blood is then carried to the queen for regurgitation.
  • But, this is non-lethal. The larvae live through the process to become more blood sucking adults.
  • But, under a microscope you can see that the larvae are covered in scars.
  • Talk about a rough childhood.
  • It’s important to note that ant blood is technically not blood.

Know the Difference!

Trigger Warning for anyone like Carlos who gets the hemogibbies

  • The substance that flows through bug bodies is called hemolymph, which is the name for the invertebrate version of blood.
  • The blood of vertebrates like you me and your dogs contains red blood cells, which oxygenates our entire bodies.
  • Because we have a closed circulatory system with arteries and veins and stuff, we need blood to carry oxygen from our respiratory system to the rest of the body.
  • Invertebrates like the dracula ant have open circulatory systems.
    • Instead of veins and arteries, hemolymph flow freely through the body
    • Oxygen often permeates an insect’s exoskeleton, oxygenating their insides.
  • Because there are no red blood cells. So if you were picturing an ant with red liquid dripping from its mandibles, stop it.
    • It’s more like a yellow or clear liquid.
    • You might be thinking, “Wait! I’ve squashed an insect before and it bled red!”
    • Well, if it was a mosquito, it was probably your blood or someone else’s that it just sucked up.
    • If it was a house fly, that was actually red eye goup that helps them filter color in a certain way that’s too complicated to explain in this episode. ( Click the link for more.)

Back to the Fact

  • Hemolymph is mostly water but also contains other stuff like ions, carbs, lipids, glycerol, amino acids, and hormones.
    • That’s right, bug blood is full of fats and sugars, which makes it a good food source for animals like the Dracula Ant, certain types of wasps that also feed on their larvae, and spiders.

Outro

Ants share food and even blood. Their social corporations would be touching if they weren’t so gross! But we can learn a thing or two from these sinister little insects. Proverbs 6 tells us to take a page from the ant’s work ethic, but we can also learn a thing or two from them about sharing.
