The Grass Demon Udaspes folus is a small but prominent butterfly found in Asia that belongs to the Skippers, or Hesperiidae family. It is regarded as an occasional pest of ginger and turmeric.

The Grass Demon prefers forest edges or clearings where dappled light is present. Its black and white colouration may have evolved to take advantage of the dappled light in these areas. The pied pattern which seems prominent in the open is effectively disruptive in the shade and the butterfly is difficult to locate once it settles down.
It is a bold insect and not easily disturbed. It usually flies in the shade among bushes and under trees keeping low and close to the ground. From time to time, it takes short flights, and, occasionally, much longer excursions into the open clearings. Its flight is quick and the path is very erratic making it very difficult to track when in flight.

When basking it sits on the upperside of leaves of herbs or bushes with its hind wings pressed flat against the surface and its fore wings held half open at an angle above the hind wings.
This butterfly also has a unique wing flashing display most often seen just after it has alighted on a leaf. It will move its hind wings down toward the leaf surface. When the hind wings are about halfway down the fore wings also start moving downwards. On the upward beat both wings are moved simultaneously till the hind wings come together. Then it again begins the downward beat. Each beat is performed very slowly and the butterfly is very conspicuous during this time.
This display is unique since no other butterfly is known to display the capability of moving forewings and hindwings separately.
