You know what I like about this blogging project of mine? The fact that there is always something new to learn. It’s the universe, after all, and I will never ever even begin to contain it.For instance, this is one of the Lampyridae family of beetles, the fireflies, lightning bugs, glowworms. But hold on a moment: this and several of its fellows (yes, the long, elaborate antennae tells us they’re male) were flying in the daylight. This is one of the dark fireflies, day-fliers who do not glow or blink or light up magically. So how can it be a firefly? I mean, besides looking like a firefly? Well, what unites the Lampyridae is that they all have larvae that produce bioluminescence. Yet not all the adults do: and this is one of them, a member of the Lucidota genus. Instead of using light to attractive females, these dark fireflies do it with chemicals; that’s why the antennae are so elaborate, and why they were so busy, waving in the air, searching for female Lucidota pheromones in Van Cortlandt Park. I recently attended a talk by entymologist Sara Lewis, who discussed her study of fireflies and her new book, Silent Sparks: The Wondrous World of Fireflies. Afterwards we all walked into Prospect Park, where a fog after sunset made for wondrous effects. And yes, we saw fireflies, Big Dippers (Photinus genus). And everybody was happy.
Here’s one of the night-flying blinky-blink lightning bugs, a Photinus Big Dipper, hiding out during the day.
Lewis begins with the near-universal fascination with fireflies, one of those insects are that loved wherever they are found, which is not something you can say for most insects for most people. I still delight in seeing the blink of fireflies at night: there is something awe-inspiring and magical about them. There are some who say that science takes the awe out of the world, but I think this is silly. Knowing that bioluminescence is a chemical process may demystify it, but doesn’t make it any less amazing. The fact that evolutionary processes resulted in such things makes it infinitely more fascinating than the snap of the fingers/tentacles notion of creation by some kind of superior being/presiding genius.
