The butterfly is locally common in secondary and montane forests at low to moderate elevations (Alt. 10 - 900m). Both sexes visit flowers.
All photo records of Ideopsis vulgaris and Ideopsis similis from Cambodia are considered to be Ideopsis similis. Identification by specimen and further distributional studies in Cambodia are required.
