Watching a pair of flies go round and round aimlessly in my bedroom. They are clearly lost.
Humans are better than flies because shortly after developing flight, we developed air traffic control to avoid this problem.
Flies have been at this for a gazillion years and they don’t have ILS or navigation beacons or anything.
Bit shit of them really. Flies, do better!
@goatsarah They may not be being crap -- there's a particular spot in my house where small (and thankfully inaudible and non-bitey) flies circulate, up to a couple of dozen on a hot day with windows open -- I don't think it's a chemical cue, I suspect it's a consensus fly nightclub spot, à la https://en.wikipedia.org/wiki/Tokunagayusurika_akamusi#Swarming
