Where is the Elaphrus Beetle?

Dan Duran, assistant professor in Drexel University’s Department of Biodiversity, Earth and Environmental Science, has just embarked on a search for the marsh ground beetle, which also goes by the Latin name for its genus, Elaphrus. It is found along muddy stream banks in temperate regions like ours. It's an effective "indicator species" because it's adversely affected by run-off, like road salts and agricultural chemicals--that make it into a stream without being visible.
