For the last in our series on invasive species that can be mistaken for natives, here’s one of the trickiest: phragmites, also known as common reed.
In honor of National Invasive Species Awareness Week, we’re posting daily “dupes” — invasives that can easily be confused with native species. Today we’re featuring two tiny freshwater mussels that couldn’t have less in common.

Experts said the pest’s eggs, which will hatch in spring, are able to withstand the recent arctic blast.
Over the last five years, agencies such as the U.S. Fish and Wildlife Service and Minnesota Department of Natural Resources have employed a new seek-and-destroy strategy that uses turncoat carp to lead them to the fish’s hotspot hideouts.
