The lanceolated warbler (Locustella lanceolata) is a small grass warbler of the warbler family, Locustellidae. The bodies of these birds are brown, white, and yellow in color. The bird cannot be spotted easily in their habitats as they are skulky bird species. There are two recognized subspecies of the lanceolated warbler, L. l. hendersonii, and L. l. lanceolata. The genus, Locustella, is a derivation of Latin 'locusta', which means 'grasshopper'. Also, this name refers to the insect-like song of the common grasshopper warbler and more species of this genus. The specific scientific name Lanceolata is a Latin term for 'spear-shaped,' which refers to their streaked breast. Johann Jakob Kaup, a German naturalist, introduced the Locustella genus in 1929 with type species as common grasshopper warbler (L. naevia). There are 23 described species in this genus. Also, 11 genera consist of 66 species of these insectivorous songbirds. This family was previously placed within the Old World warbler 'wastebin' family.
