The butterfly is locally common in montane forests at low to moderate elevations (Alt. 30 - 700m). This species is distinguishable by only examination of the male genitalia.
Larsen (2004: 129) treated chapmani as a distinct species, despite a lack of evidence. I disagree with this view and therefore treat it as a subspecies of penicillata, as previously.
