In our daily walks along trails at the Zurqui de Moravia site near San Jose and here in the Monteverde Cloud Forest, we take advantage of fallen trees and broken tree limbs to test out our botany knowledge, add a few more families to our life lists, and poke around for hidden snakes, frogs, and especially insects. I don’t have the heart to peel off the carpet of mosses, filmy ferns, and flowering orchids to find beetles and bugs. Documenting the arthropod community living in the phytotelmata of a bromeliad is destructive sampling – tearing leaves apart and using forceps to spread the soil. Fortunately, this is not the focus of my current research nor permitted by my Costa Rica research permit; thus, I am spared the conflict of attacking these gorgeous bromeliads for cryptic insect treasures.
I visited Monteverde in June 1994, as a student in a field course led by former KU professor, Dr. Michael Greenfield. This was before my own current students here were born! Back then I was enchanted by the forest, its birds awaking me as they began singing from about 4 am, by the clouds drifting in with their misty moisture, and the overwhelming diversity of plants. The old field station inside the reserve was a wooden 2-story construction, with poorly lit rooms and scary showers. My student companions and I then complained of the wet and cold, while enjoying being far from home in this extraordinary forest.
In 1951, 11 American Quaker families migrated to this area in protest of the Korean War. Costa Rica had abolished its army and was an attractive destination. As the community established and grew, developing a low-key farming model, biologists began arriving for research. The reserve was established in 1972 to protect one of the world’s most diverse and virgin forests, with 6 ecological life zones and more than 2500 species of plants.
Today, Monteverde has grown, like Costa Rica, into a super-successful model of nature tourism and conservation. The road, now paved, passes through the towns of Santa Elena and Monteverde. My jaw dropped with the number of shops and hotels. The new field station offers fine dining, its own gift shop, and a small army of workers and guides. The forest is still a wet and cold place and the station still has heart-stopping frigid showers.
It is a remarkable site to view the busloads of school groups and families and their uniformed guides arriving early, even before 7am, paying the entrance fees and heading off on the trails. More wondrous is that over 70,000 visitors come here annually to learn about biology and ecology!
Before the start of the program I had to pleasure of traveling around Costa Rica with my dad. It was an experience unlike any I have had before. First off I loved all the different chances to experience the difference in culture. For a little while we lived with a Costa Rica family. That was a very eye opening experience, because it showed me that their everyday life isn't that different from ours in the states. Also, eating home cooked food every day we were with them gave me good insight to the typical meals; breakfast never changed, and dinner was essentially the same every time but with a different protein. The other thing I now find very cool is the plants. When I was traveling with my dad I saw a lot of the plant order that we are here to study and didn't even know it. However, now that I have some field experience under my belt I realize I was surrounded by them. I didn't realize how abundant they were here, and I never would have guessed at all the different organisms that live on the plants. I'm looking forward to the rest of our research. All in all it has been a great time so far, and my favorite place was the Manuel Antonio National Park, so I am excited to be returning there for the weekend.
There’s a chase through the jungle in “Indiana Jones and the Kingdom of the Crystal Skull” that incorporates the giant, terrifying Siafu ants. It’s over-the-top and kind of silly seeing them essentially devour one of the characters; but watching actual footage of them in a nature documentary, working as a horde to eat an animal, now that’s scary. However, it’s not until you’re actually in the jungle and the forest floor is covered in ants that will bite you to hell that the panic sets into your heart.
But not all the ants here are intimidating. Right now I’m looking at a busy mass of tiny black ants going to town on a dead fly on my cabin floor. The first day that I saw three or four groups like this in my room I freaked and stomped them out like Godzilla, but now I let them be. Observing leafcutter ants on a trail is actually inspiring to see, as creatures so small carry materials so much bigger than them and work together with such efficiency.
But the frightening ants have left a more lasting impression on me. A few days ago as we walked on a trail deep in the jungle, we came across the notorious Bullet Ant, which is longer than a fingernail and has the most painful bite (of any insect here?). Professor Chaboo was bitten by one a previous year and said the pain sears like a bullet wound for 10-15 minutes. We took a few pictures as it sucked sap from a tree, until it began crawling down toward us, and we knew it was time to move.
Shortly thereafter, we entered what we’ve dubbed “The Gauntlet.” Rains from the night before flooded some underground ant nests, so the trail was covered in roving ant colonies. One stretch was so fully lined with ants that we were afraid to simply walk through it, so we each composed ourselves before making a terrified, expletive-heavy dash across it. As far as I can tell, I made it through without ant bites, but my ankles fell victim to the merciless chiggers instead.
One of the biggest surprises for me on this trip was how different Wayqecha, the first field station, was from my expectations of the rainforest. That’s because Wayqecha is in a cloud forest: high in elevation (3000m), cool, and relatively dry. However, we still got soaked on our first hike when the area received its first rain in three weeks.
When we left Wayqecha, we travelled down the Kosñipata valley from the clouds to the tropics, spotting waterfalls along the road and dense vegetation that grew more vivid in its green color. At Villa Carmen, the second field station, I really felt like I was walking into the jungle, as this area fit my expectations of the rainforest.
While I had prepared for the heavy humidity and higher temperature here, I wasn’t ready for it after living in the comfort of Wayqecha. It took me several days to adjust. But the much greater density and diversity of beautiful plants, flowers, and insects make it worth it.
The almost daily rains required a change in routine as well. Sometimes they come late morning or early afternoon, giving us a siesta period to rest after lunch before returning to fieldwork around 2-3 p.m. Other days a downpour begins in the middle of the night and continues until late morning, which limits us from hiking the trails until the afternoon. We wake up too early here for my taste, so I’m not too upset about the extra rest the morning rain provides.
Yesterday I learned to collect beetles with a method called beating. This involves a sheet (fabric or nylon) on a wooden or PVC frame and a stick (e.g., a broom handle) to collect insects from trees and bushes. You hold the sheet under the branches with one hand and hit the vegetation with the stick with the other hand. The insects fall from the plants unto the sheet, and you can then quickly collect them by hand or using an aspirator. It sounds pretty simple, but for a first timer it is not so easy. Being 5’1” tall, it was a little difficult for me to reach some of the overhanging tree branches. Having a long beating stick made for some awkward moves. You also need to be quick to catch the insects before they recover from shock and fly away. Beating needs a lot of practice. Overall, it is an interesting to way to collect insects and also get some personal aggression out at the same time.
