Some color variations of E. era could also be confused with E. micheneri. While E. era typically has a red band transversing the wings, some individuals have an incomplete band restricted to the middle of the wings, formed out of red shapes. Note though that the red in these individuals is much larger than in micheneri, usually angled upwards and not in a cube shape; the smaller red mark on either side is also bigger in E. era and connected with the larger marks, giving the impression of a continuous red patch. This is not the case in E. micheneri, where the small and larger red marks are distinct from one another.
