As annoying as houseflies are, they don’t weigh very much. It would take about 12 million of them to weigh a pound.
Flies also have a developed sense of taste, but they taste with their feet.
Though flies weigh very little, there is an insect that is related to crickets which live in New Zealand that can weigh over a pound. The insect is called a giant weta and a smallish one is pictured here.
