Water Penny

Water pennies are a type of segmented beetle that go through a complete metamorphosis. The young, which live in water, resemble pennies.Fact|date=February 2008 The larvae feed off of algae, larvae and feces. Presence of water penny larvae in a stream can be used as a test for the quality of the water. Among the pollution sensitivity categories sensitive, somewhat-sensative, and tolerant; water pennies belong to the sensitive category.
