Water Pennies: Flat as a Pancake

I recorded this back in January and am finally getting around to launching it today. This episode features a fascinating little beetle larva that clings to rocks in rivers and in wave-washed lake shores. Water penny beetle larvae were first mis-described as isopods and later the error was fixed. You can find them on river rocks where they graze on periphyton. The episode art is from photos taken by then UVM student Erin Hayes Pontius when she worked in the lab at St. Michael's College. It shows a water penny (genus Psephenus) on the left and a false water penny (genus Ectopria) on the right.
