They are not of this earth.
There are similar things here in the antipodes which are vaguely known as sandflies or bushflies. They're brown and armoured and look like the spacecraft from Lexx when you see them close up. They love to do the wait-around-knowingly-until-you-resurface thing if they find you while you're swimming and you try to hide underwater.
Also, you can't kill them. They literally re-form like the Terminator. I have crushed one until it looked like a car wreck, surely dead, and then buried it several inches deep under hot sand. The fucker ominously resurfaced five minutes later, shaken but not stirred, and ready for more carnage.
