I wonder if any friendly entymologists can help me get to the bottom of the following lavatorial condundrum. I nearly posted this is 'Heatwave 2017', but a thread about toilets is the nearest I've ever been to the Dark Web, so why not live a little?
I've had the odd conversation over the past few years about the declining numbers of house files in recent years, as most people seem to remember them being a considerable nuisance in the past. In 2017 I've been troubled (at home) by only one or two flies that didn't stay long and just one large, noisy, and very annoying bluebottle. Most people round here (SE England) also seem to agree there've been very few wasps this year. I can only recall one or two getting into the house, and those were only half alive. If memory serves, which it doesn't always, we spent hours on end in Ye Olden Dayes rushing about with fly sprays and papers and shovelling their little corpses from windowsills. Not so any more, so it seems - and the electric tennis racquet gizmo hasn't left the cupboard for ages.
Yesterday (Friday 1st Sept, in case the date is significant). I left for work on a slightly chilly morning and travelled to a workplace only about twenty miles away yet where the weather is often quite different from at home. By late morning the sun was out and it became much warmer than in recent days - quite summery in fact. Unusually, I was bothered by a common or garden indoor fly doing all the stuff I remember from childhood in particular, such as buzzing loudly around one's earholes and making a point of crawling on anything you might be about to put in your mouth; coffee mugs, glasses, biscuits, sandwiches...which again brought to mind the fact that this seems to be a rarer experience these days. I just assumed the flies were feeling frisky due to the sudden rise in temperature.
On returning home in the evening I went into the bathroom, for personal reasons, to find something unusual - something in fact which I have never observed in my life nor ever heard described.
In the toilet bowl were eleven big adult house flies floating in the water at regularly spaced intervals. It was clear that they had passed away some time during the day and were now beyond help. Obviously the Amityville Horror came to mind.
I'd been gone for quite some time (about 11.5 hours) and apparently the weather had been far chillier than the Indian Summer the living fly and myself had enjoyed at work...but the house was unnocuppied with no heating on - so it wouldn't have been invitingly warm. The window was open a crack, so they must have made their entrance that way for some reason.
Therefore my question is: why the heck would nearly a dozen house flies decide to come in through the window and then commit mass suicide by mounting a kamikaze (ha! I said 'khazi'...) mission by dive-bombing a toilet bowl?
The toilet, I would like to make clear, was, and is, spotlessly maintained to the very highest of standards. I've seen a few that weren't, but never with dead flies floating in them.
I'm puzzled by this self-destructive insectoid behaviour. As I said, the house was empty, so no one was playing Leonard Cohen records or anything.
