whitish. Similar to S. exigua, especially females. Spodoptera cilium with hind wing veins white, veins infuscated with gray in S. exigua.

Underside ground color pale gray; outer margin with black spots; reniform spot darker, indistinct to absent.
Hindwing: Ground color white; gray scales along apex and outer margin; fringe white (female with fringe light brown to pale gray at apex and median line becoming white toward anal veins). Underside ground color white; costal cells C and Sc cream speckled with pale gray scales; outer margin spots absent (female with pale gray spots in middle of cells, becoming indistinct toward anal cell).
Abdomen: Dorsum gray; venter cream and gray; disto-lateral black spots on sternites absent; 8th tergite with spiculate patches absent on caudal margin.
Genitalia: Uncus curved in basal half; slender, gradually narrowing toward pointed apex; setae numerous, elongate, weakly developed. Tegumen lacking a pair of projecting arms on upper third. Costa sinuate (Figs. 309, 339). Costal process an
indistinct swelling bearing setae located in middle of costa; perpendicular to costa of valve. Cucullus apex round; not produced. Anellifer with lightly sclerotized plate bearing setae absent. Ampulla elongate, slightly curved with a pointed apex; extending to moderately below apex of valve (Figs. 309, 339). Clasper proper triangulate with pointed apex. Clavus absent. Sacculus broadest at base, gradually tapering distally; apex truncate. Valvula narrower than valve; slightly differentiated from valve, apex not separate; apex pointed; indentation absent. Coremata reduced, closely appressed to sacculus; no distinct lobes. Juxta a rectangular band, median process elongate, expanding into an apical plate, ventral margin straight to convex. Anellus membranous. Vinculum round. Aedoeagus straight; coecum smaller in diameter than shaft; patch of spines absent on apex of membranous sheath surrounding aedoeagus. Vesica curving dorsally; moderately elongate, 0.75-1.0 length of aedoeagus; apicobasal cornutal patch a narrow ribbon; length moderate, extending to before middle of vesica; cornuti in form of minute flat granules; lateral cornutal patch a narrow elongate ribbon; composed of granular spines with a very large basal spine; dense cornutal patch on apical diverticulum; distal cornutus absent.

Spodoptera cilium

provided by wikipedia EN

Spodoptera cilium, known variously as dark mottled willow, lawn caterpillar and grasslawn armyworm, is a noctuid moth found throughout much of sub-Saharan Africa and western, southern, and south-east Asia and several countries in southern and eastern Europe. It is a migrant to northern Europe and has been recorded at least nine times in the United Kingdom.

The larva feeds on Oryza.[1] It is sometimes a pest.
