Are all mosquitoes alike?

No. Mosquitoes have been around for millions of years. In that time, they’ve diversified into about 3,000 species worldwide. They have successfully adapted to climates from the arctic to the tropics. Some mosquitoes bite humans while others prefer other animals and some even just sip plant nectar; some transmit diseases, while others do not; some are active during the day, others at night; some prefer to breed in clean water, others in dirty ponds and swamps.
