I heard that everytime a fly lands, it lays eggs. So when a fly lands on your arm, is is laying eggs?  And also is it true that flys only live for one whole day (24 hours)?

No, flies definitely don't lay eggs every time they land.  They lay their eggs in suitable locations, and even more importantly, only the female flies actually lay eggs, so about 50% of the flies that land on you will never, ever lay eggs under any circumstances.

There are a couple of answers here. One could be because you have a light in your pool and like most bugs they are attracted to light. Second is because they have a very short life span hence the word "june" a one month bug. And three because they are very heavy with little wings and its hard for them to fly for long periods at a time.

"BANGKOK - Doctors found around 50 maggots in the ears of an 84-year-old Thai man after he went to hospital complaining of an itch." (1)\n\n"Myiasis is the infestation of tissue with fly larvae, commonly referred to as maggots.  It is widespread in the tropics and subtropics of Africa and the Americas, and occurs with significantly less frequency in most other areas of the world.  The infestation is most often subcutaneous and produces a furunculoid or boil-like lesion, but it is also known to occur in wounds and certain body cavities. ." (2)\n\n"In early September, fly larvae (maggots) were seen in each of two stool specimens [*] collected on different days. These larvae were identified as living third-instars of Muscina stabulans, the false stable fly." (3) *from a 12-month-old girl\n\nI honestly can't look for any more; I'm getting queasy. But clearly, maggots can and do live in humans. If they are just under the skin, they cause raised, red infections.

They will stay on the ground regardless of the speed. They are not aerodynamic, so they won't naturally rise in the air and fly because of speed unless they had wings added to them.

That is because the fly IS moving at the speed at which the vehicle is moving. By the way, it DOES NOT hover at the same place. Suppose the fly is a little fast than the car , then it appears to the fly that the wind-shield is moving towards it and it then adjusts it's speed to remain in the same place( if it chooses to). In the same way in all other cases, it modifies it's speed.\n Someone above pointed to inertia. Remember inertia only acts if the fly or any other object is in contact with the moving object. Otherwise it does'nt come into picture.

How big was that cup?! I've found dead flies in my drink, but never, never a dead squirrel. I think you should contact Guiness Book of World Records.

Its what you want to argue or prove...a statement that the entire paper will prove and support...THE MAIN IDEA\n\nExample- Chickens cannot fly for extended periods of time due to the evolution of farming habits, lack of muscle tissue, and wide variety in their diet.....then you explain each point...what evolution has done, why the lack muscle tissue, and how their diet consists of many things so finding food is easy...all will lead to the conclusion as to why they no longer fly

It is some type of fly. I have seen several also, and when i called my mom she says that they are flies.

They are likely following air currents-Flies dont think about where they are going-they dont really "think" at all, in terms of making decisions.  THey just have simple reactions to ari currents, heat, light, and chemical sensations (food)-If they are circling, its because there are air current moving in a circular motion, and they are following those.

You need to breed it with a fly showing phenotype 'a' (which you know is genotype aa - the double-recessive).  \n\nIf any of the offspring also show phenotype 'a', then your fly was Aa.  (I.e. it is producing both Aa and aa offspring with the aa mate.)\n\nIf all offspring show phenotype A, then your fly was AA.  (I.e. it is producing only Aa offspring with the aa mate.)

If the fly flies in while the box car os still, the doors are shut and the fly doesn't land, the fly will move relative to the outside, not the train.  Once the fly lands, It will take the properties of the train as its frame of reference.  So, it will move around the box car as if it were still.\n\nIf the box car is open, you are "opening" the system, in that the box car is not it's own environment.  Turbulence, etc, will affect flight.

OK. these things are insects- so they can be killed.\n\nFirst of all, face the problem. If you have head lice, they are also probably in all your apartment, also clothes, hats, etc. Also anyone you are in close contact with.\n\nFor the hair- it is easy. Simplest solution is to shave all hair. I do mean ALL hair, because lice lay eggs on any hair (including eyelashes, armpit hair, pubic hair) they get across (they look like silvery streaks and are almost impossible to get rid off by conventional means)\n\nIt also means you have to boil all your bedclothes, clothes, caps, etc. and spray all over the flat (including the walls and behind/above/under the bed) with some good bug killer- preferably the kind for crawling insects (longer lasting). I hope you're not allergic.\n\nIf you don't want to shave all hair, cut it as short as possible then soak in vinegar for a couple of hours at least (covered in a towel) then comb out with a special comb- very close set teeth (some pharmacies may have them). You have to repeat it at least once a week for 3-4 weeks. This is because new lice hatch from eggs every 2 weeks or so, so you have to kill them before they have a chance to lay new eggs.\n\nFor mature insects it is easy enough- rub oil or butter on your hair, leave it on for 3-4 hours. Blocks the bugs breathing holes and they die. Not quickly, but they die eventually.\n\nHot iron treatment may suffice- both for clothing and for hair. Not as effective as shaving, but worth a try.\n\nRemember you got the bugs from somewhere- so you're likelly to get them again from the same source\n\nIn any case, they are alive and therefore they can be killed- just "stay the course". A bit like fighting the Taliban- some say hopeless- but if you persevere long enough they quit living

If you only have one canary then it can not be fertile but if you have a male and female then you may see some babies soon.If they arent fertile she will throw the eggs out of the nest herself.

Well, if you and your friend were aardvarking in bed, you don't have much to worry about because the sheets would be changed and laundered.  Bye-bye proof.\n\nIf you were being creative and it wasn't in the bathtub or shower, it is there until it is washed away.\n\nSperm can live for 3 - 5 days in a hospitable environment.  If every womb were an ideal environment, there would be many more pregnancies.\n\nThe answer to the unasked question: while sperm can live for several days, there is only 24 hours for conception, UNLESS your partner does something biologically unusual, such as ovulate twice (source of fraternal twins).

If the egg is unprotected then wear gloves & transfer the egg to a make shift nest made up of grasses, leaves, ect & keep it warm in the late evening & night with a thick towel. Around 10am if it is about  78degrees or greater remove the towel. after the baby is born worms & insects hunting will be your job\n\nGood luck

This is as Serious Question, especially when tackling West Nile Virus, Malaria, Dengue, all vector borne disease.\n\nGoogle this on the web, there was a recent report about Rain and Butterflies (Slightly larger than bugs) They are also frighten of rain, as it is dangerous to them, the relative size of the water droplet, would harm them.\n\nBugs, usually try to hid from the rain, going into overhangs,  under large leaves, seeking shelter when they can find it.\n\nGood Question.  Next point, ever wonder where Flies goes after dark.

1.5 chickens lays 1.5 eggs, thus 1 chicken lays 1 egg as there is a 1:1 correspondence.\n\n1 chicken lays 1 egg in 1.5 days, so 1:1.5 is .6:1, one chicken will lay .6 or 2/3 of an egg in one day.
