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.
It will eventually mate and lay eggs to begin the cycle all over again. Most adult butterflies will live only a week or two, while a few species may live as long as 18 months. Images in this section are of the life cycle of the black swallowtail on one of its host plants, fennel.
