Abstract

The conglutinates of Ptychobranchus greeni, a freshwater mussel, mimic aquatic dipteran larvae in shape, size, and coloration. They possess a terminal adhesive filament that may function as a holdfast to attach the conglutinate to rock or gravel substrata and maintain them in the riffle and shoal habitats of potential fish hosts. The decline and subsequent disappearance of P. greeni from much of its historic range may be partially explained by sedimentation and eutrophication within these habitats that limit the ability of the conglutinates to attach to the substratum.
