But horseflies are interesting. And beautiful, in their own way. In my ceaseless quest to bring you cool info about astonishing beasts, I didn't immediately swat these savages away. Yep, I took one - quite a few, actually - for the team in order to get some shots. That'd be my leg, above. Denim is no barrier for the rasping swordlike mandibles of these purveyors of pain. I still have welts. But to truly learn, one must experience. Go out and get yourself bit by a gigantic Tabanus horsefly. You'll come to understand them better.
This is a female. They, not the males, are the biters, as blood is an essential ingredient to successful reproduction. I'm not saying that ALL females are thirsty bloodsuckers, but these are. I don't know the exact species of this fly, but it was quite striking with a good look; the huge spacesuit goggle-like eyes are wonders of nature, and the bright orange antennae created a striking contrast to the somber brown hues of the body.
Once the fly has settled on your meaty blood-filled substrate, it goes to work. Jabbing those formidable "teeth" into your hide, it rips, slices, and dices. This is not done with clean scalpel-like precision. Rather, our tormentor blasts its way into your flesh with harsh jagging rips, causing the blood to flow, which then the Dipteran Dracula eagerly laps up. This is basically an insect roadside bomb strategy. No stealth here. Just roar in, blast out a chunk of the victim, suck out as much blood as possible and get out before being swatted into oblivion.
There. I hope you have a great appreciation of the horsefly.
