I think it's a case of wanderlust, crayfish will often be found crossing
roads during the spring here in Louisiana. Often it's because their original
habitat is drying up or the water has become uninhabitable because of a
build-up of tannins which is called blackwater. Very low O2 levels!

I once sent a full grown Procambarus clarkii to John Brill and he reported
the same thing, a dry crayfish wandering the floor in his darkroom.
