Which would it be?
For me, it would most surely be the mosquito. I hate the damned things. I don't get bitten that much, and when I do the itch of the bites doesn't linger long.. it is that peevish, high-pitched whine right by your ear, just as you are drifting off to sleep. And, of course, the little pests vanish almost as soon as you flick on the light.
It happened last night. It is really hot here by West Coast standards and we are sleeping with all the windows open... I'd just started to approach that drowsy partially awake stage (despite the clinging heat)... and then I heard it.... that immediately detectable whine...Grrrr... I'm prone to insomnia as it is, I don't need mosquitoes exacerbating the problem..
So, anyway, there is my candidate for a species that doesn't need to exist
btw, to clarify, I'm not seriously advocating the annihilation of any species, this is just for joking around
