Indus Valley Civilisation species "Oryza nivara". This led to the local development of a mix of "wetland" and "dryland" agriculture of local "Oryza sativa indica" rice agriculture, before the truly "wetland" rice "Oryza sativa japonica" arrived around 2000 BCE.

Elasmopalpus brown anterior and distal margins. The larvae feed on a wide range of plants but prefer grasses. Recorded host plants include a number of economically important plants such as "Phaseolus vulgaris", "Beta vulgaris", "Brassica oleracea" var. "capitata", "Cucumis melo", "Cyperus esculentus", "Zea mays", "Vigna unguiculata", "Phaseolus lunatus", "Avena sativa", "Pisum sativum", "Arachis hypogaea", "Capsicum annuum", "Oryza sativa", "Secale cereale", "Sorghum bicolor", "Glycine max", "Sorghum sudanense", "Saccharum officinarum", "Ipomoea batatas", "Lycopersicon esculentum", "Brassica rapa" and "Triticum aestivum". They tunnel into the crown of their host plant, severely weakening large plants and often killing young seedlings. They spin silken tubes near the
