Crocus Geometer

This is why I am not going to make a specific species ID. Rindge (1978) examined 1,886 specimens (1441 males, 445 females) and made 261 genitalic dissections. He stated: "No one has found a reliable way to recognize the species as yet except by genitalia. The adults of all species in this genus are, for practical purposes, externally indistinguishable from one another, as they are almost identical in color, maculation, and size."
