In all, 180 species have been recorded from this locality, which is situated in one of the biodiversity hot spots in India. It has been made out that the spot be given due attention both by the Entomologists and Ornithologists. The fruit piercing for juice sucking and skin piercing for blood sucking behaviour of certain Ophiderinae taxa have been quoted to attract the attention of Lepidopterists in India. It has also been emphasized that the life history studies and location of the larval host plants of non-pest species are essential from the conservation point of view.
