This is pretty funny … someone came to my blog today to find out whether glow worm poop glows. [Since I wrote this, few days have passed when a keyword search of "glow worm poop" hasn't brought somewhere here. What a thing to be known for!]
The answer is no – that’s because the glow worm doesn’t poop. The glow that they make is their form of excretion. But rather than just launching solid or liquid waste, the glow worm converts the leftover matter into light that’s used to attract its prey. The glow worm dangles silky threads from their spots in their home caves. Insects see this and thinks they’re seeing stars, and fly toward the light. They get caught in the threads. Then the glow worm eats them, absorb the nutrients, turns the excess matter into light and begins the cycle again.
Really, that’s pretty fabulous. It takes stuff in, but leaves nothing but heat and light behind. That’s an incredible bit of evolution. And certainly, it has to be the envy of every mechanical engineer. That means no glow worm poop … at least not in the usual way we think of droppings.
If you’re interested in seeing glow worms, there are a number of places in the world to do so. Of course, I’m pretty partial to Waitomo, New Zealand. Here are a few related posts:
There’s not a lot else going on in Waitomo, but it is one of the more relaxing places I’ve ever been. Go there to get away from it all … and to enjoy some quality caving. If you look at the hotels story above, you’ll also find out about Woodlyn Park, where you can stay in everything from a converted cargo plan to a hand-built Hobbit Hole. So that’s another good reason to pick Waitomo as the place to find your glow worm adventure.
