Protoplasa fitchii Osten Sacken

Its broad wings with prominent anal angles make this common “primitive crane fly” easily recognized.  Its other characters include wings with five branches of the Radius vein; a single Anal vein; cell 1st M2 closed, elongate; a supernumerary cross vein in cell M3.  This is the only species of this family existing in our area.  Their wings have distinct brown cross bands bearing pale spots in the center of each band.  The immature stages occur in wet sandy soil at stream margins.  The adults were collected from herbaceous vegetation and low shrubbery near the margins of streams.  This species is widely distributed in eastern North America from eastern Canada to northwestern Florida.
