The Horsfield's Baron (Tanaecia iapis puseda). This species prefers the sanctuary of the forested areas in Singapore, although they are sometimes found in public parks and gardens. Males are more often seen than females. The male of this species exhibits 'territorial' behaviour, where it perches on a few favourite locations and dives to chase away any intruders into its space - even a stone thrown into its domain of supervision will be similarly chased away!
