Distribution. Cuba ( Busck 1934), USA: Florida ( Hall 1983) and Louisiana ( White et al. 2007), and Ecuador (new record). According to Heppner (2002) this species is likely to also occur in Mexico.

Remarks. Previously the only known host plant of Elachista saccharella was sugarcane ( Saccharum ) ( Busck 1934; White et al. 2007). We found larvae mining the leaves of unidentified Poaceae grasses (most probably of the genus Muhlenbergia ( Figs. 45, 46 View FIGURES 45 – 46 ) growing on a roadside at an altitude of about 1800 m ( Fig. 4 View FIGURES 2 – 4 ). The larva makes a full-depth, straight, linear mine, which extends towards the leaf tip, about 10–13 cm long. It pupates in a flimsy cocoon ( Figs. 47, 48 View FIGURES 47 – 50 ) on the underside of a leaf. The cocoon varies in density and orientation of silk filaments covering the pupa. The pupa is highly modified, with lateral ridges produced into short or long curved acute spines ( Figs. 49, 50 View FIGURES 47 – 50 ).
