'The lord in his wisdom made the fly, then forgot to tell us why.' Ogden Nash. Pretty much sums it up about the great beard in the sky.
Wasn't it Singapore that irradicated flies, paying people to kill them, and then had to reintroduce them because of the time decaying matter took to rot away without their help? Searched but if you put the word fly into a search engine holidays come up aggressively.

Beelzebub had to have something to rule over, every demon needs a job.
I bet it's great fun to actually be a wasp, though.
