I've actually seen this at my hive too. The ones that I've observed eventually crawl back into the hive. I've seen them like this also some 20 feet away from the hive too (but I gave up watching those to see if they'd make it back).
I figured in the end, it was the circle of life if they made it back or not. I have a lot of eggs in my hive, so I figure that I could stand to lose a few and not have the natural on-goings of the hive too effected.
Great video!!
