Good grief! There's not a lot to go on.... ok, so we can see most of it, but it's not like it has anything particularly outstanding about it at first glance. It almost looks like a cross between a wasp and a dragonfly, though the head does have a certain ant like quality too... I'm a bit baffled and not big up on insects as there's not a lot of variety round here.
I was actually going to say dragonfly but it doesn't really have the color scheme of one. Knowing @Wreybies and where he lives, it could be some kind of monstrous flying cockroach.
Nope. I picked that image in particular because it gave scale with the guy holding it. Nope and nope. Points for humor, but nope. Sooooo close!
If it is an ant we have only approx. 22000 species to choose from. If it lives in Puerto Rico, that narrows it down to 39. If it even is an ant, that is. ETA: In hindsight maybe I should not have posted this, as I'm actually studing biology but don't seem to know what an ant looks like...
Close enough that I'll give it to you. It's actually the king (drone), also known as a Sausage Fly. It is the largest not-queen ant in the world. When the Sausage Fly is mature and a driver ant column comes by, he smells it and is attracted to it. The driver ants clips his wings (and sometimes his legs) and take him to their queen for some whoopie. The queen driver ant is an even more disturbing looking critter.
It's not your vision @obsidian_cicatrix, and it's not in the deep sea. Hint: There's a reason the image is unclear.
