Melitara subumbrella
''Melitara subumbrella'' is a species of snout moth in the genus ''Melitara''. It was described by Dyar in 1925. It is widespread in western North America, from southern Alberta and Saskatchewan to southern Arizona, central Texas,〔(University of Alberta E.H. Strickland Entomological Museum )〕 southern New Mexico and south-eastern California.
The wingspan is 35–52 mm. The forewings are long, narrow and uniformly gray or brownish-gray, generally with dark lines along the veins. The hindwings are broad and white, often with grayish or grayish-brown margins. Adults are on wing from March to May. A second generation may occur on some locations, with adults on wing from October to November.
The larvae feed on ''Opuntia basilaris'', ''Opuntia ficus-indica'', ''Opuntia macrorhiza var. macrorhiza'', ''Opuntia atrispina'', ''Opuntia phaeacantha'', ''Opuntia polyacantha'' and ''Opuntia violaceae var. macrocentra''. Young larvae are gregarious and prefer to feed on cactus fruit. Later instars tunnel in the cladodes and final instars may tunnel into the underground parts of the host plant. Pupation usually occurs in debris.〔(Cactus Feeding Moths )〕 Mature larvae are white with light purple cross-bands.
