Many rituals involve local species. In Sikkim, Lepchas are known to use over 370 species of animals, fungi, and plants. According to the Nepal Census of 2001, out of the 3,660 Lepcha in Nepal, 88.80% were Buddhists and 7.62% were Hindus. Many Lepchas in the Hills of Sikkim, Darjeeling and Kalimpong are Christians. The traditional clothing for Lepcha women is the ankle-length "dumbun", also called "dumdyám or gādā" ("female dress"). It is one large piece of smooth cotton or silk, usually of a solid color. When it is worn, it is folded over one shoulder, pinned at the other shoulder, and held in place by a waistband, or "tago", over which excess material drapes. A contrasting long-sleeved blouse may be worn underneath. The traditional Lepcha clothing for men is the "dumprá" ("male dress"). It is a multicolored, hand-woven cloth pinned at one shoulder and held in place by a waistband, usually worn over a white shirt and trousers. Men wear a flat round cap called a "thyáktuk", with stiff black velvet sides and a multicolored top topped by a knot. Rarely, the traditional cone-shaped bamboo and rattan hats are worn. Traditionally, the Lepcha live in a local house called a "li". A traditional home is made out of logs of wood and bamboo and rests around 4 to 5 feet (1.2m to 1.5m) above the ground on stilts. The wooden house with thatched roof is natural air conditioner and eco-friendly. It is interesting to note that the traditional Lepcha house has no nails used in the construction and it is seismic movement friendly since the weight of the house is rested over a large tablets of stones and not planted in the soil. The Lepchas are mostly agriculturists. They grow oranges, rice, cardamoms, and other foods. The Lepchas are known for their unique weaving and basketry skills. They also have a rich tradition of dances, songs, and folktales. One popular instrument used by the Lepchas is a four-string lute that is played with a bow. The Lepcha are largely an endogamous community. The Lepcha trace their descent patrilineally. The marriage is negotiated between the families of the bride and the groom.
