The orange-bellied long-nosed squirrel (scientific name: Dremomys lokriah) belongs to the family Sciuridae, also known as the Himalayan orange-bellied long-nosed squirrel and the Tibetan long-nosed squirrel. It usually lives in the cycad forest at an altitude of 1500-3400 meters or the woods at 2000-2600 meters. It feeds on nuts and plants, and occasionally eats insects. This species has a sharp call. The orange-bellied long-nosed squirrel breeds when the temperature is slightly higher from May to August each year, with 2-5 cubs per litter. It especially likes to move in the cycad forest. It builds nests in tree holes. It is diurnal, good at moving in the bushes, and moves quickly. It feeds on plant fruits, young branches and leaves, mushrooms and some epiphytes (such as usnea), etc., and also eats insects.
