Notes

The butterfly is locally not rare in dry forest at low to moderate elevations (alt.250m - 900m) and is frequently found at hilltops. Males are territorial on canopies and are often found sympatrically with Virachola perse, however this species is generally less common than Virachola perse. Examples of dry season males tend to have an obscure orange patch on the UpF.
