During hot summer when I walk in forest I feel shower of water drops. These drops are not specific to any tree species. This shower is due to forest cicada. http://www.youtube.com/watch?v=8nRiXADag74 [In Traditional Healing, the Healers having expertise in Entomotherapy and Entomophagy use it with different herbs as medicine.] You can feel falling water drops in shade of Shorea robusta trees specially during summer. Shorea is one of the trees used in Traditional Tree Shade Therapy of India.
