They get no respect, the two-winged insects known as flies. The biters, bloodsuckers, shit-eaters, in-flesh laying parasites, maggot-spawners.
Ooooog, you say, why are you doing this to me on a Sunday morning?
Well, at least they’re not Republicans.
There are an estimated 17 million flies for each and every human. We’d be drowning in excrement and corpses if not for all these flies, or at least the types that do the dirty work. But as Erica McAlister, a curator of diptera at London’s Natural History Museum, tells us, they do a lot more besides. There are also, for instance, vegetarian flies and pollinators. Indeed, chocolate depends on Forcipomyia genus midges for pollination. Paradoxically — or humanly, if you prefer — the expansion of cacao tree cultivation has meant clearing the forests in which chocolate midges live. Uh-oh. McAlister notes that cultivated cacao trees already have a very low pollination rate….
Obviously in love with her life’s work, McAlister’s enthusiasm is infectious.
And speaking of infection (this is a book review by Borscht Belt routine, evidently…) it’s not the mosquitoes — yes, they’re types of flies — who cause trouble; it’s the disease they carry. And they carry those because of the blood they need to produce their young. As vampires know, blood is very rich food; there are even tiny little midges who tap the blood mosquitos fill themselves with.
Cue up Jonathan Swift:
The vermin only teaze and pinch
Their foes superior by an inch.
So, naturalists observe, a flea
Has smaller fleas that on him prey;
And these have smaller still to bite ’em,
And so proceed ad infinitum.
Thus every poet, in his kind,
Is bit by him that comes behind.
I’ve read the coffee bean is reliant on biting flies for flower pollination. Respect indeed!!
