The Giant Redeye is the largest Hesperiid in Singapore.  It is very rare and has so far been observed only within the Central Catchment Nature Reserves.  The wings are deep brown above with pale yellow spots on the forewing.  The paler underside, shown in the photo, has pale bluish scaling in the apical area of the forewing and hindwing, where it forms three or four obscure transverse bands.
It is a very shy butterfly and is rather alert and difficult to capture.  It normally stops in well-shaded localities with wings folded upright as in the photo.
The caterpillar is known to feed on the banana (Musa spp.) and Bertam Palm (Eugeissona tristis).
