Abstract

Here we describe the complete life history for Methona confusa confusa Butler, 1873 and Methona curvifascia Weymer, 1883 from eastern Ecuador. Each stage from egg to pupa is described and illustrated. Descriptions of first instar chaetotaxy and instar durations are also reported. Both species were found feeding on Brunfelsia grandiflora schultesii Plowman. Mature M. confusa larvae have 12 transverse bands that are all yellow in color, including one on segment A9 as observed for M. megisto and M. themisto. In contrast, M. curvifascia lacks a transverse band on segment A9, having 11 transverse bands in total that are white in middle segments and orange in anterior and posterior segments. The pupa of M. confusa and M. curvifascia differs in the arrangement of spots on the thorax dorsum.
