Winners and Losers: The Insect World


I’ve come to know quite a few new species of the insect world since arriving in Nicaragua. Some have impressed me, or terrified me (or a bit of both). Others have caused me to ponder what, if he were alive, Darwin would have said to justify their continued existence. I’d like to take a few moments to highlight some of the shining stars, and a few failures of evolution (as far as I can tell. Please feel free to discuss these with a entomologist and let me know what they think.

The All-Stars

Termites (termitas)
Tiny, ever-present, highly organized, and incredibly destructive. How does one get rid of termites in Nicaragua? As far as I can tell, you don’t. Instead, you go about your business, resigned to the fact that part of your house will one day be a pile of dust, having been eroded by the constant chewing of miniscule, ever-hungry little insect jaws. Which, by the way, you can hear.

Butterflies (mariposas)
You know those giant, vibrantly blue butterflies that you see sometimes tacked in display cases? I saw one flitting by in the wild the other day. It took my breath away. The bright colors of the surrounding flora just couldn’t compare to that iridescence.

Mosquitoes (zancudos)
My dislike of mosquitoes has grown immensely now that I live in partially enclosed spaces. I have to respect them, however. They survive despite being universally reviled (except, I suppose, by those species which feed upon them). They multiply rapidly. They evolve to feed at different points during the day so that every variety gets an opportunity to dine, free from competition. And dine they do. I have no idea how they manage to bite me as much as they do, but every day I end up with not one, but a patch of new bites, in different spots. Hands and feet are definitely the worst.

Scorpions (alacranes)
Yes, I know they aren’t “insects”. I don’t care. They’re on this list because they scare the crap out of me. Evolution definitely did its work well early on, and decided to let well enough alone. These creatures are prehistoric evil. How is it fair that it should be equipped with pincers, jaws, and stinger? Cheaters.

The Rejects

Giant black beetles (ron rones)
Sure, the size is impressive. Those mandibles look like a force to be reckoned with. But they probably won’t be using them against you or much else, as they have the sad tendency to flip over on their backs and spend hours or days flailing their little legs in a futile effort to right themselves. Eventually they die of natural causes (exhaustion; starvation; stupidity), or get crushed.

Giant Flying Ants (hormigas voladoras)
Another instance of impressive exterior, faulty interior. These insects are pretty massive. The buzzing of their wings is loud and grating. Their mandibles look fully capable of inflicting significant damage to exposed skin. And there is the strength in numbers factor: these babies swarm. They also die a few hours after they appear. And snap, crackle, pop when you step on them.

Slugs (babosas)
Large enough to be indiscrete, slow, and lacking any form of defense. What is the purpose of a slug, other than to eat plants and leave mucous smears? I found one hiding in my sandal the other day (note to self: do not drop guard. Check shoes before putting them on. Toe-slug contact in the dark is unsettling). Six hours later, it was still there. I dislodged it with a pen and threw it into the yard. Worthless.

Briefly Winged Larva-Looking Bugs (no idea)
I really don’t understand these bugs. They arrive in droves when it rains. They have beautiful, iridescent wings that carry them to every conceivable surface in and out of your house. And then…they lose their wings and become awkward, highly squishable larvae-like things. That then become squished smears. Seems pretty pointless to be equipped with fully functional wings if you’re planning on dropping them after the first time you land on a solid surface.

Word of the Week: chinche – insect of the small and biting variety
