I study a population of Bislineata in Northern Ohio. The stretch of stream and surrounding woods contains approximately 300 individuals. The enigma is in the males I've seen. From all that I've read, the Southern males are distinguished from Northern by a downward projection from the sides of the upper "lips". All of the males I see have this trait. Is this normal of some populations? Does the range of the Southern species extend up to Lake Erie? Any thoughts are welcome and appreciated! I hope someone can solve the riddle for me.
