What's the lifespan of a fly?

Common Housefly Life Cycle;

Each female fly can lay up to 500 eggs (in five batches of 100 eggs each). The eggs are white and are about 1.2 mm in length. Within a day, the larvae (maggots) hatch from the eggs; they live and feed in (usually dead and decaying) organic material, such as garbage or feces. They are pale whitish, 3-9 mm long, thinner at the mouth end, and have no legs. At the end of their third instar, the maggots crawl to a dry cool place and transform into pupae, colored reddish or brown and about 8 mm long. The adult flies then emerge from the pupae. (This whole cycle is known as complete metamorphosis.) The adults live from half a month to a month in the wild, or longer in benign laboratory conditions. After having emerged from the pupae, the flies cease to grow; small flies are not young flies but the result of insufficient food during the larval stage.
Some 36 hours after having emerged from the pupa, the female is receptive for mating. The male mounts her from behind to inject sperm. Normally the female mates only once, storing the sperm to use it repeatedly for several sets of eggs. Males are territorial: they will defend a certain territory against other males and will attempt to mount any females that enter that territory.


Housefly pupae killed by parasitic wasp larvae. Each pupa has one hole through which a single adult wasp emerged; feeding occurs during the wasp's larva stage.
The flies depend on warm temperatures; generally, the warmer the temperature the faster the flies will develop. In the winter, most of them survive in the larval or pupa stage in some protected warm location.
Some species of wasps can parasitize and kill the pupae.

Female lays 5-6 batches of 75-120 oval, white eggs on moist manure or garbage. Eggs hatch in 10-24 hours. Larvae reach full size in 5 days emerging as adults about 5 days latter. They are ready to mate within a few hours after emerging. During warm weather two or more generations may be completed in a month. Males live for 15 days, females up to 26 if they have access to milk, sugar, and water.

The lifespan of a fly depends on your AIM!

too long.

The average fly will live for 36 hours. Unless it is swatted.

ill different because they never know what day there gonna get swatted or taken by a frog!!

I have heard anywhere between 24 -48 hours.

If i fly isnt puposfully killed by a human or another animal, they can often live up to 36-56 years. This doesnt often happen because they are usually killed but... i know that they can live up to this age because once, i found a baby fly and put it in a big big cage... and it lived for 56 years!!! :)

five days

The life span of flies varies according to temperature and strain on feeding. For standard strains at 29 C life span is 25 days mean and 32-34 max., while at 25 it is 60 days mean and 80-92 max.Their reproduction rate is also temperature dependent but at 25 C and 70% humidity it takes approximately 10 days from egg lay to adult, with a 2-3 day lag until maximum egg laying rate. At lower temperatures down to 16 C, flies will develop slower and live longer in a temperature dependent manner.

half a day cause it gets decapitated helplessly by the giant hand of a human which is like 100x bigger then the fly, then its body implodes in on itself and blood smudges vilontly on the wall or window (just dont smash the window) then its organs drop out everywhere like on resident evil :(
Rip alot of flies.

Personally, I haven't seen flies live long lives. Use of fly-paper, while irritating to deal with, will help. Avoid noxious gas if you can - that stuff isn't pretty. I do believe however, similar to fleas, flies are attracted to light.

An old remedy for fleas is to put a tealight lit in a big pot of water. The tealight should be floating in the center. The flies will be drawn to the light, not see the water and drown upon impact if their wings get wet.

Try that too. ;)

1-4 days usally 1 day because everyone and everything hates them.

a fly just flew by, SPLAT!!!!!!!


ha ha :]

I love science. Thats what I do for a living, work at a biotech company. Im going into medicine though. :-)

don't know guess they just need to live life at it's fullest. Lol :p
