In most cases, malaria is transmitted through the bites of female Anopheles mosquitoes. There are more than 400 different species of Anopheles mosquito; around 30 are malaria vectors of major importance. All of the important vector species bite between dusk and dawn.
When replayed at normal speed, time appears to be moving more slowly. A term for creating slow motion film is overcranking which refers to hand cranking an early camera at a faster rate than normal (i.e. faster than 24 frames per second).
Early silent films only came in at 14 frames per second, which is why they appear herky-jerky to the human eye. We've been at 24 fps for quite some time, and though I can only comment on my personal experience with The Hobbit, the film felt sped up, almost as if I was watching it in 1.5 time.
