Butterfly populations are a very good indicator of the health of an area's ecosystem !!
Sulfur butterfly, (subfamily Coliadinae) consists of any of a group of butterflies in the family Pieridae (order Lepidoptera) that are bright yellow or orange and have a wingspan of 35 to 60 mm (1.5 to 2.5 inches).
Sexual and seasonal dimorphism in pattern and colour occur in many species.
The pupae are attached to a twig by a posterior spine and a girdle of silk.
Hatchling butterfly caterpillars are nearly microscopic. They grow thousands of times their hatchling size before they pupate.
Adult butterflies are attracted primarily to red, orange, and purple colors.
Adult Sulphur butterflies are also well camouflaged when they rest. They normally land on a leaf or item that is very near the same color as their wings.
