Description
This Hesperiid is rather rare and has been observed on only a few occasions in the nature reserves. When seen, it was usually feeding along some muddy track or on bird droppings. The butterfly flies rapidly, and when in flight, only the white undersides of the hindwings are visible, making the Skipper appear smaller than it actually is. As many of the Tagiades species also demonstrates such characteristics, Odontoptilum angulatum angulatum may have been mistaken for one of the more commonly occuring Snow Flat (Tagiades) species.

Habitat & Habits
There are two Odontoptilum in Malaysia and Singapore, and the other species, The Banded Angle (Odontoptilum pygela pygela), has not been observed in Singapore, even though it occurs in nearby Johor's forested areas.
