Wasp belongs to the Order Hymenoptera, which includes bees and ants also. It is in fact one of the largest insect groups. Tropical wasps build their hives in tall trees and steep corners of the mountain edges, all habitat commonly found in the Periyar Tiger Reserve. The wasps lay their eggs and hatch their young in beautiful hives made out of clay mixed with their saliva. 

The sting of some tropical wasps can be highly toxic, so it is important to keep a safe distance.
