Prairie Crayfish

The Prairie Crayfish (Procambarus gracilis) is one of 8 species of crayfish in Iowa.  It's the only one that lives in grasslands or prairies.  What makes this crayfish so spectacular to me is that it digs burrows for itself in the prairie away from water.  The burrows can be 1.5 to 2m deep.  They have a vertical shaft down until the burrow hits the water level where it becomes enlarged and filled with water.  The burrows are marked with mounds. The amazing thing about this crayfish is the amount of deep clay soil particles it moves to the top of the burrow where they can be eroded which plays a big role in the health of ecosystems!  The prairie crayfish can live 3-4 years.
Here is a Prairie Crayfish mound! See if you can find one on your next adventure.  Prairie Crayfish are most active in June.
