To many, Labor Day marks the end of the summer season, even as Memorial Day marks its beginning. Many see Labor Day as their last chance to get out and take a vacation before summer is gone, and many workers get a two-week annual vacation period with Labor Day Weekend right in the middle of the two weeks off.
The lifespan of a hover fly is similar to other flies. They can  live anywhere between 15 to 30 days and it all depends on the  climate and temperature they are in.he common housefly (suborder Cyclorrhapha) generally can have a life cycle of 15 to 30 days. Four distinct stages characterize its life cycle: egg, larva, pupa, and adult.
The fly emerges from the pupa, and its development is complete. Adult flies live between 15 and 30 days. Some female flies can begin laying eggs within a few hours after emerging from the pupa, and others need to be at least 2 days old. Female adult flies lay eggs throughout their lifespan.
