About Tirathaba rufivena (Walker, 1864)
Tirathaba rufivena (Walker, 1864) has a wingspan of approximately 26–30 millimetres, which equals 1 to 1+1⁄4 inches. More or less developed ring-like markings (annuli) at the middle and end of the forewing cell are connected by a white streak. Sometimes a spot at the base of the cell is also joined to these markings by the same white streak. The inner margin, vein 1, the interno-median interspace, and veins beyond the lower angle of the cell are streaked with crimson. It has a dark marginal line along the edge of the forewing. The hindwings are a plain pale yellow or orange yellow. The larvae of this species are an agricultural pest that feeds on Cocos nucifera, Nypa fruticans, Elaeis guineensis, Musa species, and Phaseolus species. Caterpillars most commonly attack male flowers. Infestation causes young fruits to abort and leads to the growth of underdeveloped fruits. Severe attacks can cause the entire plant to wilt and delay overall plant development. These larvae are not borers, and feed only externally on host plants.
