Comments:
This fly has an 8 mm body length. It blew this bubble over about a 3 minute period of time. It blew it out and then sucked it back in. There's a considerable amount of discussion about this behaviour on the Internet but as far as I can tell there is not yet a solid, scientifically accepted reason for it. One of the more popular theories is that it may be a method of temperature control. Does anyone know for certain?
