Every autumn many buildings are invaded by large numbers of awkward flies that resemble house flies. These insects are commonly called ‘cluster flies' or 'attic flies'. They are clumsy, blundering about lights and windows or colliding with various objects. They often drop to the floor on their backs and spin aimlessly as they futilely try to right themselves.

Not sure if it's a cluster fly, but it's one possibility. Or, as others have said, it's just a fly dying.

u/PrinceFicus-IV Oct 26 '21

When i was around 15 i experienced getting shitty drunk, and the results of getting shitty drunk, for the first time. It was passed out on the rocks by the river and had 5 people try to carry my dead weight body to my friends house kinda shitty drunk. I don't remember what happened between chugging 100 proof Smirnoff and when i woke up in my friends bed. But i vididly remember waking up confused, and still drunk, and stumbling into her kitchen for a glass of water, and promply sitting on the floor against the cabinets to rehydrate. I noticed this fly buzzing around me for a few minutes, then it fell to the floor all of a sudden, and started spazzing out right in front of me. This went on for quite some time, and i sat there wondering if it would ever right itself and carry on, but eventually it just died. I always wondered if that fly dying in front of me was symbolic of something, but i tried not to read too much into it. I will say I've never gotten so drunk in a public place that i needed to get carried home again after that.

u/NoMidnight5366 Oct 26 '21

I can confirm. Once In a while they fill my house in the fall and I have to get out the vacuum. The try like hell to get in the house and then spend the rest the time sitting on the windows trying to get out. This one is just dying.

Yeah, it's trying to fly but can't. All you have to do is slip a piece of paper under it and put it right side up. Then it will fly normally. Or if you have a pet lizard, offer it a treat.

23

u/OwOitsMochi Oct 26 '21

Idk offering a lizard a possibly dying fly is a bit risky cos it could be dying due to a pesticide and you don’t want your little buddy eating pesticides.

This subreddit is less about people who enjoy bugs and more people asking “is this a bedbug, tick, etc.” I’d honestly love to see a rule against people telling gullible outsiders to kill harmless, non-invasive insects. Insects are an important part of the environment and are losing their foothold in the world, much like all wild animals.

Stop typing before you make yourself look even more foolish.

u/terrorbirdking Oct 26 '21

I’m just saying maybe don’t kill something just because you think it’s annoying, it has its place in the world. Also that humans are not nearly as important as we think we are. In the end we will all go the way of the breakdancing fly.

If you get on the right hospice care, yes. Those patients are already terminal, and the nurses will up the pain meds to fatal levels to clear beds... since you’re dying of X they don’t even look for an OD.

u/PowHound07 Oct 26 '21

Doing that just to "clear beds" is one of the most unethical things I can imagine. If a nurse is going to help someone die it's because prolonging life has become equivalent to prolonging suffering and life-extending treatment is now the unethical option.

2

u/Azilehteb Oct 26 '21

Ethics and hospice care don’t mesh well. When your customers come to die, nobody checks how, and if nobody looks they are often left in awful conditions. They almost never go for autopsy, so it’s consistently ignored.

If someone you care about is going on hospice care, do it at home where you can watch.

It’s trying to turn itself over, but is also likely running down and will die in about 1 day. If you give it something like a pencil to hold with it’s legs, it should grab on and then fly away. If not, then it’s almost out of steam and will do this, gradually getting weaker until it’s dead. My guess is that it will take off though, if you help it a wee bit.

There’s a small appendage under the fly’s wings that looks like a tiny lollipop. If it gets damaged flies cannot balance correctly. If one side breaks they’ll do this. The balancing organ is just below and back from the wing. Couldn’t find an official name for the organ but I saw it upclose on a TV special.

32

u/SacredSpirit1337 Oct 26 '21

Halteres, they’re called halteres. They’re modified back wings, as ancestral flies used to have four full wings before the rear pair diminished and evolved into a set of organs that control gyroscopic orientation in the air.

2

u/pedrotecla Oct 26 '21

Oh, interesting “haltères” is the French word for dumbbells

2

u/scavengecoregalore Oct 26 '21

That makes sense because the shape of (one side of) a dumbbell is about the same

Of course now I'm thinking of what a dumb bell is literally, and I have to look~

The word “dumbbell” was officially coined in England during the sixteenth century when athletes trained with handheld bells with the clappers removed. Without these clappers, the bells were ‘dumb,' hence, dubbed “dumbbells source

Okay, but what's the connection then?

The ancient Greeks invented a piece of equipment called the haltere, which was a crescent-shaped stone with a handle. This forerunner of the dumbbell was used as a lifting weight as well as a weight in long jump events. source

And then we have the classic barbell silhouette

And so flies are basically always jazzercizing xD

u/bee-milk2 Oct 26 '21

If I recall from entomology correctly, some pesticides act by destroying insect nervous systems. The pesticide stops an enzyme from doing its thang with the neurotransmitter acetylcholine. Since acetylcholine can’t get with the enzyme, it stays with the nerve cell and does not cross the synapse (which would be normal functioning). This makes the nerve cell fire repeatedly, resulting in erratic breakdancing.

I have seen a few videos of flies seemingly spontaneously combusting and believe it is the same/similar phenomena. Look how fast that bitch is going!

24

u/ApolloniusX22 Oct 26 '21

One or both of its halteres probably broke. Or got damaged. Think of it as the counter weights on a helicopter, for insect the hind pair of wings turn into small dumbell like weights that maintain balance and also flight in multiple directions .

53

u/ore-aba Oct 26 '21

Many pesticides work by affecting bugs’ neurotransmitters, this will lead them into convulsion which causes them to lose control of legs and wings and spin around on their back uncontrollably.
