What happens to insects, bees/ants that get stuck on busses/trains?

Insects instinctively follow the light. That is why they buzz against the wind shield inside your car and they try to get out of your house by flying towards the windows, light bubls and your TV or computer monitor. In nature, if they accidentally get trapped, they can often find their way out by following any source of light because it will often lead them to the outside since there is no glass in nature to block their way out. If they cannot find their way out, then they will eventually pass away due to hunger.

They are doomed, as we all are.

They wouldn’t get stuck on buses or trains. A bus or a train would open its doors many times a day. The insects could use that time to leave the vehicle.
