Sex and deposition of type unknown. Gibson (1919) provides a key for the identification of the species of the genus among which is this species but mentioned as Gargaphia lasciva . Pennington (1921) mentions G. lunulata for the región of “The Litorial” without further information of provinces or localities, Monte (1938) mentions the species for the Chaco province, Drake & Poor (1938) for Cordoba and, Guilbert & Montemayor (2010) for Salta. Bosq (1937) cites for the first time the species for Uruguay without information about provinces or localities. Monte (1937) provides a photograph of the species and Silva (1956) an illustration. The life cycle is described and illustrated in Ajmat et al. (2003). This species feeds on many important South American plants from several families: Euphorbiaceae ( Euphorbia sp., Manihot sp., Ricinus sp.), Leguminosae ( Cassia sp., Glycine max (L.)), and Malvaceae ( Gossypium sp., Hibiscus sp., and Urena sp.)
