Every day here is one for the books, but today was especially special.

We started the morning with a surprise. We would be performing an experiment to measure the abundance of bugs in the canopy vs the forest floor, as well as how attracted they are to nutrients. We are going to take our data based on how many of the bugs fall into these “pitfall traps,” which is liquid in a vial that the bugs get stuck in. We had a water control vial, and a nutrients vial. But here’s the surprise-guess what we were using for nutrients? Our pee! It was definitely weird, but sometimes that’s what you have to do for science!

We then headed out to set up the pitfall traps. We each had four vials-two controls (water) and two nutrients (urine). We would put a water and a urine vial on a tree to catch bugs from up there, and then one of each buried up to the brim in the ground to catch the bugs from the forest floor. We spread out our vials, so each tree with a pitfall trap was about ten feet apart. Setting up the traps took up the rest of the morning, so we came back for lunch. Along the way I saw some crickets-there was a small brown cricket with beige legs in the leaf cover of the ground, and a dark brown cricket under a rock. We also saw a small jumping pit viper in the middle of the trail and an eyelash viper coiled on a log! The eyelash vipers are very elusive, so it was exciting to see one.

For the afternoon, we were focused on leaf cutter ant nests! We found a young (<1 year old) nest in the clearing by the research station. We dug next to the nest, and we came upon the chamber below the ground that contained the fungus garden! The leaf cutter ants bring the leaves they cut up to the fungus garden to feed, it, and it in return grows nutrient-rich so the ants can feed upon it. Professor Solomon scooped out some of the fungus and found the queen! She was huge-almost the size of my thumb! After we took a look at her, we put her back and sealed the nest.

We then went to look at a bigger nest, to see how it was different. We were digging in one spot, but no ants were coming out. The trip was not fruitless, in fact quite the opposite! We found a Mexican burrowing frog, which is usually hard to come by because they live underground.

We then moved on to another nest, which had no frogs, but was teeming with ants. We saw that there were more types of worker ants, and that the fungus garden chamber was bigger. I caught one of the biggest ants-the soldier ant, which is specialized to protect the colony. I wanted to see how strong she was, so I let her bite me, and her long, sharp mandibles drew blood even through a callous! The nest was really cool to look at, but we sealed it up and moved on.

We had to do a bunch of presentations before dinner, but afterwards, we went on a night hike! We walked to the Frog Pond, a dried-up pond where we had seen red-eyed tree frog eggs the day before. Tonight, we saw two Morelet’s tree frogs, which are critically endangered! We also saw a ton of northern cat eye snakes, one of which we watched feed upon the tree frog eggs ☹ The rest of the snakes were in the canopy, which brought the day’s snake count up to nine.

I also saw some cool orthoptera! There was a giant grasshopper atop a palm frond, with beige and brown coloring. It was really high up, so it was difficult to identify. There was also two different medium sized brown orthopterans-one was sitting atop a leaf, and one was hanging out with the Morelet’s tree frog! The one on the ground sort of looked like the white kneed king cricket, and the other like a brown dead leaf katydid, but it was hard to tell. There were also some tiny crickets, but I didn’t get a good look at any of them.

The rain forest has been super cool, and so far I have managed not to get as many bug bites as I did at Glover’s Reef. I will keep you all updated about what we get up to tomorrow!
