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.
The slimy, gelatinous drain and sewer walls contain from 30 to 200 drain fly eggs, which hatch at room temperature within 32 to 48 hours. As the larvae feeds, they mature in 9 to 15 days. Drain flies start out as oblong eggs, pale, elongated larvae with a suction cup under their bodies, pupae, and then adults.
