A Van de Graaff can thus be used to accelerate particles up to reasonably high energies: moving an electron through 1 V gains it an energy of 1 eV, so energies of over 20 MeV are achievable by this method (and more if accelerating nuclei with greater than a single electron charge).
They locate females by listening for the sounds of their wings, which run about 250-500 beats per minute. The mosquitoes join, and the males pass sperm to the females, perpetuating the mosquito life cycle. Once their job is done, male mosquitoes live three to five days. The females tend to mate only once, but live considerably longer, depending on how much warmth and moisture is in their environment.
These are the four distinct stages in an average house fly's life: 1  Egg: Depending on the size of a female house fly, she can lay up to 500 eggs in a three to four day period.2  Eggs are white in color and are usually less than half and inch in size.3  Larvae: Larvae are commonly referred to as maggots. This process take about three to six days and is where the maggot encases inself in a reddish-brown skin where the final stages of development take place. 2  Adult: Once the adult house fly hatches from the pupal stage, it has an approximate life span of 15 to 30 days.
