Eublemma is a of small in the Erebidae, containing over 400 distributed across tropical and subtropical regions worldwide. The genus was described by Jacob Hübner in 1829 and has undergone taxonomic revision, previously placed in Noctuidae or as the type genus of Eublemminae. Several species are economically significant as of scale insects, particularly E. amabilis, which attacks lac insects (Kerria spp.) and has been investigated as a agent.

Identification
Palpi upturned, reaching just above the vertex of the with a short third joint. Male minutely ciliated. and smoothly scaled. Legs short with moderately hairy tibiae. Forewings with somewhat produced and depressed apex; 6 and 7 from angle of , veins 8–10 stalked from before angle. Hindwings with veins 3,4 and 6,7 from angles of cell. Larva with two pairs of abdominal (reduced from the usual four pairs in Noctuoidea).

Distribution
in tropical and subtropical regions. recorded from Africa (widespread across sub-Saharan and North Africa), southern Europe, Middle East, Central and South Asia, Southeast Asia, Australia, New Guinea, Pacific islands, and the Americas. Several species with restricted distributions on oceanic islands including Socotra, Madagascar, New Caledonia, and the Canary Islands.
Ecological Role
of scale insects (Coccoidea); E. amabilis documented as predator of lac insects (Kerria spp.) and fig wax scale (Ceroplastes rusci). Some may function as biocontrol agents in agricultural systems, though hyperactive in early instars of E. amabilis reduces laboratory survival rates.
Human Relevance
E. amabilis is a pest of lac in India, causing 20–25% damage to lac encrustation. Conversely, the same has been evaluated as a agent against insect pests in Vietnam and India. Target of fungus Isaria fumosorosea as potential microbial control agent.
