The butterfly is locally very common in montane forests at moderate to high elevations (Alt. 900 - 2500m) and is frequently found at hilltops. Males often come to the banks of streams and puddles to suck water.
The taxon aornus from W.Malaysia is conventionally regarded as a synonym of lagela, however I consider it to be a distinct subspecies. The relationship between Appias lalage and Appias pandione is still uncertain. The differences are unclear, especially in females. Further taxonomic study, including DNA analysis, is needed.
