There’s nothing that centers me quite like a torrential downpour can. I’ve always loved the scent of the Earth after it’s been washed clean. I find it calming and restorative. (And I just learned that this scent is actually the odor of soil bacteria!) I’m writing this blog as thunder is rolling through the gray skies and fat raindrops are pelting the ground. The sheer velocity of the rain is blowing a breeze through the screen windows.
I really can’t describe how oddly serene it is to sit on the floor of a non-air conditioned, wooden research station in the middle of the rainforest as the sky empties itself. It’s humbling. All life here depends on this rain, and today marks the first huge rain of the season. That means that the forest is about to come to life, even more than it already has been. We may get to witness the nuptial flight of ants, in which newborn queen ants and males take to the air in a gargantuan swarm to mate. Amphibians will be more active. It’s going to be a different forest now.
Other than enjoy the rain, we also collected our urine samples from a couple of days ago! On the way back from collecting the traps, I found a dying swallowtail butterfly on the side of the road being eaten by ants. It was was an elegant creature even as it was being gnawed on.
Poor little guy 🙁
Nitrogen an extremely important element that is vital to most life forms. It’s a surprisingly scarce element in a place as rich in life as the rainforest is. Because of this, we figured that more arthropods would cluster to our urine, which we used as a nitrogen source, in areas that are more nitrogen-poor. The forest canopy is actually more nitrogen-poor as compared to the forest floor, so we expected more critters to end up in our traps that we placed in the canopy.
After we sorted and counted the species of bugs, insects, and other invertebrates that we discovered in our pitfall traps, we actually ended up finding some pretty cool results. It was a long afternoon of sorting, counting, and identifying dead insects and bugs that were soaked in our own urine, but we ended up getting to present to a new group of college students that arrived at the station today. I think they were slightly grossed out by our poster, titled “To Pee or Not to Pee,” but I think our presentation went over pretty well.
Today was again a quiet day on the Lepidoptera front. I only spotted 4 blue morphos, all of which evaded me. I know that they purposely fly extremely erratically in order to escape from birds, and they’re certainly doing a great job of escaping from me. Alas.
