I’m getting ready to umpire a ballgame when I’m like 20. Come out of the room five minutes before game time, and both teams have gone sprinting to the dugouts because this massive swarm of wasps (bees? Maybe bees… it was over 20 years ago) came buzzing right over the field the game was supposed to be on. Heading southeast. Partner and I nope back into the room for a while.
Anyways. The insects continue on doing whatever wasp- (or bee-) like activities they were doing and we play the game.
Game goes well. I get changed and go home. Home is somewhere between 5-10 km southeast of the ballpark.
As I park and get out I notice that the family is freaking out. Swarm of wasps (or bees) had just buzzed their way over from the northwest and taken up residence in one of the walls of our carport.
Sounds to my uneducated ears like bees hiving. IIRC a bunch of individual bees go out and find potential spots for a new hive, then come back and communicate with the hive details like where it is and what it’s like. Then the hive picks one of the spots and all of them who are going to go to the new hive go.
That’s exactly what it was. But the sheer odds of them settling on my house the same day as I worked a game a fair distance away at a park that happened to be in their path to their new home? Pretty fucking high.
