Although mosquitoes can be annoying, and some are serious health threats, they can play an important role in natural communities. ENY-727S, an 8-page Spanish language illustrated fact sheet by Jorge R. Rey, presents an unbiased view of this versatile organism. Includes information about the mosquito life cycle, exactly what is happening when a mosquito bites someone, how to avoid mosquito bites, and how they transmit diseases. The author also addresses several common misconceptions about mosquitos and provides several sources of additional information and references.
