Red Helen is a rare butterfly found in wet zone forests in all the year round. The males are fond of settling on damp earth on the roads and stream beds. When resting with open wings the forwing is drawn back over the yellow color patches of the hind wing as shown in the picture above, probably to avoid unwanted attraction of predators. Larva feeds on Zanthoxylum and Citrus (de'Abrera B., 1998) and Kudumiris[කුඩුමිරිස්] (Toddalia asiatica) (Gamage R., 2013)

The Trinket snake is a common non-venomous, terrestrial snake widely distributed in lowlands up to about 600m elevation. It can be found both in forests and anthropological habitats mostly closer to water bodies. It is active during morning hours as well as dusk and considered as a diurnal snake though nocturnal habitats have been observed too. When cornered Trinket snake expands its fore body and open mouth displaying its black color. Hence the vernacular name Katakaluwa (One with a black mouth). It feeds on rodents, frogs and lizards.
* One depicting in above photographs is a juvenile albino snake with about 36mm length, encountered in a home garden. Distinct black lines of the neck region and black streak behind the eye are faint of this specimen unlike it is with normal snakes. It had red eyes as it is always with albino animals.
