The first lesson of the rainforest I learned the hard way is to never touch anything that you can’t see. Creatures, especially insects, linger in dark crevices, under leaves, or blend in with the bark of a tree. If you’re about to fall, your first instinct is to reach out and grab anything that could possibly break your fall. However, in a place where there are more living things in a square meter than you’d like to know, that is probably the worst thing you can do. One day, while I was out on a trail inspecting a strange bug, I reached down to pick off a leaf to poke the bug with (some hardcore science going on over here). I immediately felt a stinging, burning sensation on my finger. Oh crap, I thought, a fire ant got me… again! When I turned the leaf over, though, I was surprised to see a vibrant and beautiful caterpillar.
A surprising fact about the rainforest is that it is actually hard to see wildlife. Animals are there, but in the most complex and mature ecosystem in the world, they have learned to be very conspicuous with most only coming out of hiding at nighttime. However, one group of organisms you will always see here are insects. They’re just everywhere! For this reason, I’m dedicating my first blog post about the Amazon on the insects of the forest. Their colors, shapes, sizes and abilities will really amaze those who never even thought of themselves as bug-people.
This spider remains highly unknown to science but is thought to be relatively common in the Amazon. I found this tiger spider when workers at the research station were clearing a spot for emergency helicopters. Roaming around in the cut trees, I found more bugs during this hour than my entire month in the Amazon. Although bugs are alot more common than animals, they are still hard to find as they live high up in the canopies where they have protection and food sources.
One remarkable symbiotic relationship that is apparent in the rainforest is that between some trees and ants. Several species of trees provide nectar to ants in exchange for permanent protection from other threats to the tree. An example is the lemon tree, which- because it does not have to invest in protection- can produce chemicals that makes its surrounding soil highly acidic and therefore causes a clearing around it.
A supposed stress-therapy of indigenous Amazonian people is to stick their hand in an ant hole and allow these ants to bite them for a good 10 minutes. We tried this and to our surprise, it actually causes a soothing sensation in the hand… not sure about the stress-relieving part.
We hope that, when the insects take over the world, they will remember with gratitude how we took them along on all our picnics.
