The Firefly and the Apes

firefly

An old Philippine folktale pits a firefly against a troop of apes. One day, an ape asks the firefly why he carries a lantern. The firefly replies that he uses the light to see mosquitoes and defend himself. The ape laughs and calls the firefly a coward. Insulted, the insect challenges the ape (and all his friends) to a fight. The next day, the firefly faces 1000 apes with large clubs, all lined up against him. The firefly lands on the first ape’s nose and the second ape swings his club to squash the insect. But the lightning bug flits away and the ape’s blow kills his companion instead. Then the firefly alights on the second ape’s nose. A club is swung and the second ape is dead. On and on until the firefly reaches the last ape, who piteously surrenders. The folktale ends, “Since that time, the apes have been in mortal terror of the fireflies.” (1)

Despite folktales consistently portraying apes as fools, we all know they’re actually pretty smart. The Philippine tale is one account of why apes avoid fireflies. But could there be a biological reason for this aversion? Maybe it’s because fireflies are noxious.

One firefly can kill a bearded dragon (Pogona sp.), a fairly large lizard that can grow up to 2 feet long (2). For mammals like apes, well, they probably just taste really bad. Most animals that eat fireflies spit them out or throw them up.

Fireflies do try to warn their would-be attackers through their coloration. Light and dark stripes and red markings are examples of aposematic coloration – both are found on this lightning bug. Don’t say he didn’t warn you!

Is Your Favorite Animal a WUG?

Think of your favorite animal. Is it warm and fuzzy? Or fine and feathered?

Many people think of “animals” as mammals, birds, or reptiles. Occasionally a fish, crustacean, or insect will creep in there. But, let’s face it, our view of animals is limited.

Children reflect this discrepancy when asked to draw a picture of a habitat. For instance, Snaddon et al. (2008) found that children drew ~75% mammals, birds, and reptiles in their portrayals of a rainforest. In reality, rainforest animals are 90% insects.

The rainforest isn’t unique. Most animals are insects (beetles, to be specific). It makes the Victorian hobby of beetle-collecting seem a little more understandable now.

And the Nematodes! Nematodes (roundworms) make up a surprisingly high percentage of animal species. Scoop up a trowel-full of soil from your yard, and you’re likely to have thousands upon thousands of nematodes in there.

If we can get children to understand that ecosystems, like rainforests, contain more animals than just vertebrates (and plants too!), the consequences include a better understanding of ecosystem functions and conservation issues.

So introduce yourself and your children to insects and worms (sometimes called “wugs” – worms and bugs). Attend insect-related events at a museum, make insect-face masks for play, visit natural environments, sow insect-promoting native plants (and keep careful track of all the worms in the ground), or tend an insect or worm as a pet for a couple days.

Maybe your new favorite animal won’t have fur or feathers.
