They spend their entire adult life filter feeding the zooplankton and phytoplankton from the water. It was estimated that during their peak numbers in Lake Erie, they were filtering the entire lake every day.

They can survive long periods of time as larvae found in residual water in a boat, or as adults attached to the boat. Once they infest a system, there is no feasible alternative to stop their progress.
