Belize Day 5: Inspidering and Antastic

It’s pitch black outside. You look up, and the stars illuminate the tree silhouettes and snake-shaped vines surrounding you. You flick on your headlamp, scan the ground, and see thousands of tiny, glimmering emeralds. Dr. Solomon tells you they are spider eyes, and the realization hits you: It’s a spider’s world, and you’re living in it. My new favorite hobby is night hiking.

Today, we saved the hiking for the evening and spent the morning learning about what really goes on at Las Cuevas Research Station, the site we are staying at as we study the rainforest. It is owned by Friends for Conservation and Development, a non-profit centered around environmental protection, but their work extends far beyond a single initiative. They started as a group of passionate teenagers who cherished the environment and wanted to protect it, and bloomed into an organization that hires rangers (forest monitoring), runs research stations, restores endangered species (including macaws, jaguars, game species, etc), maintains and protects cultural richness (ex. They protect Mayan remains in the caves), and help local communities. Their work and growth as a grassroots group is absolutely inspirational, and I now have my heart set on working as a ranger for them. I just need to practice carrying 80-lb weight bags places and train my knees for the steep inclines.

The FCD focuses the majority of its time and resources on protecting scarlet macaws. It is estimated that there are only 350 individuals in Belize due to extreme poaching. To protect chicks from poaching, FCD members extract chicks from the nest, raise them, and release them once they are more capable of defending themselves. We’re incredibly lucky to be staying in the only region of the Chiquibul Forest where they are found, and we see a couple fly overhead almost every day.

After lunch, we went on a hunt for leaf-cutter ant colonies–more specifically, the prized fungal gardens inside. I mentioned in an earlier blog post that leaf cutters are little gardeners who cultivate this fungus, which they eat by feeding it leaves and other materials. We wanted to see their rich harvests for ourselves.


(Fungal Garden with Queen Ant – 05/20/25)

In our search for ant hills, we set out to find both a young and an older, more mature colony. We examined how colony structures differed and changed with age. Right by the cabin, out in the open field, we saw a teeny ant hill, and Dr. Solomon started digging around the nest on the spot. New colonies are often found in open spaces or edge habitats (between the rainforest and open clearings) because the Queen ant needs to find cover asap to avoid predation, and these spaces are the most accessible. New colonies are started when a preexisting colony produces another queen, and this queen takes a chunk of fungus with her and flies high into the air to mate with a male. Once she’s fertilized, she’s set to lay eggs for the rest of her life. (She’s ___, meaning she only needs to mate once and can store the rest for the future). From there, she burrows into a new spot on the ground and starts cranking out eggs. The workers that hatch will continue digging new chambers until the hill is giant.

We walked down the trail to a massive ant mound the size of a shed aboveground that was fully mature and could have been anywhere from 15-25 years old. Underground, it easily could have been 3x more voluminous. We saw a ton of tunnels burrowing down from the surface and learned that the whole colony breathes as one unit; the tubes take in oxygen and exhale CO2.

Then, Dr. Solomon popped the question, “So do we want to rile up the ants first or start digging first? Either way, they’re going to come out.” Rile them up? These guys are no joke – they can reach the size of a thumb (from what I’ve seen) and have zinc-lined, vibrating saw-like pinchers that can draw serious blood. We all looked around at each other with big eyes, and Sam, our ant expert, volunteered to be our first digger. 30 seconds later, Sam had a battle wound (bite), and these massive guys started streaming out like a broken fire hydrant. We all started tap dancing to flick them off of our rubber boots, but with their intense pinchers, they latched on and began to chew through the rubber. In the meantime, Dr. Solomon bravely spooned some exposed fungus out of the colony. Fungus acquired, mission accomplished, and lesson learned – don’t disturb shed-sized ant hills.

After a dinner watching the sunset from our cabin deck, we embarked on a night hike to see more of the incredible creatures that call this jungle home. We breathed slowly, listening to the sounds of the jungle at night. Our our way back, we had the unexpected pleasure of seeing Belize’s National Flower, the tiny black orchid (an epiphyte!), sitting on the tree out front of our cabin. Feeling fortunate and at peace, we ended the day lying on top of the picnic and gazing up at the stars, making shapes with the stars. There is so much life out there to cherish and discover.

The Ant-Man Super Bowl: Leafcutter Nest Excavation

May 20, 2025
Hello again! As you can tell from the title, today was yet another amazing day at Las Cuevas Research Station. The day began with some light birdwatching, during which we saw some flying macaws, a toucan, and a Northern Mealy Amazon parrot. These were very cool to see!
Our morning and half of the afternoon was filled with finishing up the Cecropia experiment and listening to presentations. Before I get into what we did with the second part of the afternoon, I’ll illustrate the results of our experiment. As you can see from the poster below, the question “was how do young cecropia trees defend themselves if they’re not colonized and protected by a colony of Azteca ants?” Unfortunately, our results were inconclusive. Due to limitations on time, we weren’t able to catch Orthoptera herbivores of the same species, so that factor was not standard, and we also had the problem of hydration of the leaves (we can’t know if the leaves were absorbing water, or how much they had at the time oof weighing, because we are in a field station with only one afternoon and one morning to devote to this project.) So, the results were inconclusive, but you can read our poster pictured below. (The poster was a collaborative effort; if you know me, you know that’s not my handwriting.) After the project was over, we had a presentation from the Rafael Manzanero, director of the Friends for Conservation and Development, which is a really cool Belizean NGO that manages the LCRS, Chiquibul National Park and Forest Reserve, and they defend it. They have armed rangers, filling the role that the government plays in the US. It was very interesting to hear from him. After that, I gave my Ants Taxon Briefing, Lily gave hers on Epiphytes, and Dyllan talked about plant-insect interactions. During those presentation, we also heard from Yasmini Manzanero, the FCD’s Cultural Heritage and Karst Expert, and she briefed us on the cave system we are to explore tomorrow.
After those presentations, we had the ant-man Super Bowl: we excavated leafcutter ant nests to find their fungal garden. This was truly exciting. First, we approached the young colony (~1 year in age, 1 entrance) which is in the clearing right next to Jane’s (LCRS Manager) cabin. This is an optimal location for a Leafcutter colony because they like forest edges. The edges provide easy access to fresh vegetation for their fungus, while also providing the queen easy access to get into the ground quickly. We began our excavation by digging next to the colony, because fungal gardens (which is where the queen is) aren’t usually underneath the colony entrance, but they’re off to the side. Excavating this way minimizes damage to the colony’s structure and garden. This was so fun, because Dr. Solomon pulled out the entire fungal garden on a large kitchen spoon. With the whole garden came the queen, which was also awesome to see. She was so huge, because she has to store her sperm for up to 20-25 years and she also has to store her fungus when she leaves the colony she’s from, so she had a lot going on. It was super cool to see her.
Once we had thoroughly explored the young colony, we approached the mature colony. The mature colony was ~x years old and had many entrances. We selected this mature colony because it was raised, meaning the fungal gardens would be easier to access. This colony presented a problem though: the many hundreds and thousands of soldier ants that swarmed as we excavated. This meant that everyone had to put their things far away, and continually stomp soldier ants off their boots so they didn’t chew through them. As the ant-man, I was excited to see the horde of ants flowing out of the nest like a mighty stream and I grabbed the shovel. I was mostly successful, but I did get one battle wound. This was quite a different wound, as it hurt in the moment but it faded quickly. It also bled a lot, which was concerning (and turned my stomach bc I do not like blood very much) but that also subsided quickly. All in all, it was a great ant-super bowl and I’m super proud to have been a part of the excavating. After the wounds, we found the fungus. This fungus was interesting because a) there was much more of it, naturally, and b) It had a different texture than the fungus of the young colony. I’d be interested to compare them in a lab.
Following dinner, we had our first night hike. We saw a rare Pauroque bird (one of the “heard not seen” birds,) but the coolest thing we saw was the leafcutter ant highway. During the day, you see a couple or even a steady stream of ants flowing on these highways. At night, this highway was PACKED. It probably looked like the Katy Freeway when they brought 45, 90, and 180 to Rice. It is pictured below.
