Crocanthes glycina and C. prasinopis are similar moths that are both present in the ACT and are hard to tell apart. Both were described by Meyrick. The description of C. glycina is the later one, and it contains this comparison: "Differs from C. prasinopis by larger size, relatively narrower wings, much more oblique edge of postmedian fascia, greater development of yellow beyond it, grey hindwings and abdomen." In other words, and considering only the things usually visible in photos of live moths, the angle of the inner edge of the dark outer area of the forewing is more oblique in C. glycina, and C.glycina usually has more yellow enclosed within the dark area.
Crocanthes prasinopis is listed in the following regions:
Canberra & Southern Tablelands | South Coast | Greater Brisbane
