Bug of the week: the house fly



Most people will have experienced these sometimes pesky creatures, particularly in warmer parts of the year. Larvae can develop in all sorts of decaying organic matter like faeces, rotting vegetation, or carrion. Houseflies beat their wings approximately 190 times a second, the resulting noise sounding in the key of “F”.  Small gaps within the houseflies mouthparts allow E.coli O157:H7 bacteria to proliferate, indicating houseflies may serve as important and complex vectors of human disease.
