The following is a list of all butterflies found in the Indochinese biogeographic region (Thailand, Laos and Vietnam, Cambodia, Myanmar (formerly Burma; part of British India until 1937), Peninsular Malaysia and Singapore in the Indomalayan realm).
The climate of Indochina is subtropical in the north, tropical further south.
Indochinese terrestrial ecoregions include the Northeast India–Myanmar pine forests, Northern Triangle temperate forests, Myanmar Coast mangroves, Chin Hills–Arakan Yoma montane forests, Mizoram–Manipur–Kachin rain forests, Northern Indochina subtropical forests, Irrawaddy dry forests, Irrawaddy freshwater swamp forests, Irrawaddy moist deciduous forests, Cardamom Mountains rain forests, Chao Phraya freshwater swamp forests, Kayah–Karen montane rain forests, Northern Indochina subtropical forests, Northern Khorat Plateau moist deciduous forests, Northern Thailand–Laos moist deciduous forests, Peninsular Malaysian montane rain forests, Peninsular Malaysian peat swamp forests, and Tenasserim–South Thailand semi-evergreen rain forests.
The butterfly fauna of Indochina includes Indo-Burmese genera with a species-richness (a count of species within the genus) generally distributed from Assam to Sundaland (Sunda Islands), genera with a strong centre of species-richness in western China and the eastern Himalaya, genera with their greatest species-richness in Sundaland west of the Wallace Line and species endemic to Indochina.
