How do mosquitoes know it's night time?

@daiverd asked the Naked Scientists:
   
How do mosquitoes know when it's night time? Even if the light is on they still insist on biting and biting! AAAAARG!

What do you think?

I know this may sound a little odd but mozzies are attracted to the carbon dioxide in your breath, among other things.

They don't just bite you when it's dark, but in areas that have a relatively low population density they will be able to home in on you much more efficiently if your in the same place for more then a few hours, like your bed. This might give you the impression they are only seeking you out at night.

Apparently they can sniff you out from over 30 meters away. It's only the females that bite as they need the protein in your blood to produce viable eggs, the males live off plant nectar.

Generally they seem to be most active at dusk and dawn although I don't know why that would be unless it has something to do with the ideal temperature to lay eggs.

I wonder if it's because winds tend to die down a lot around dusk?

Pure genius Geezer, not only winds but thermal activity too, I suppose the last place a mozzie wants to be is a few thousand feet vertical distance from it's food source!

Well the main reason of mosquito attraction is the CO2 we breath out and there are other reasons too, like they are attracted to dark places.
