Field Observations of Butterfly Behaviour:
The Common Redeye is moderately rare in Singapore although its caterpillars can be found rather easily on its host plants (various bamboo spp.) on many occasions. The adults are mainly sighted at locations where there are bamboo clumps in the vicinity, and such locations could be urban parks, gardens, wastelands or the nature reserves. The adults are fast flyers and rests with its wings folded upright.
