Poaceae species in about 771 genera that are classified into 12 subfamilies. See the full list of Poaceae genera. Grasses are, in human terms, perhaps the most economically important plant family. Their economic importance stems from several areas, including food production, industry, and lawns. They have been grown as food for domesticated animals for up to 6,000 years and the grains of grasses such as wheat, rice, maize (corn) and barley have been the most important human food crops. Grasses are also used in the manufacture of thatch, paper, fuel, clothing, insulation, timber for fencing, furniture, scaffolding and construction materials, floor
Morpho its oily contents from staining the wings. Significant quantities of live specimens are exported as pupae from several Neotropical countries for exhibition in butterfly houses. Unfortunately, due to their irregular flight pattern and size, their wings are frequently damaged when in captivity. Morpho larvae, variously according to species and region, feed on Leguminosae, Gramineae, Canellaceae, Guttiferae, Erythroxylaceae, Myrtaceae, Moraceae, Lauraceae, Sapindaceae, Rhamnaceae, Euphorbiaceae, Musaceae, Palmae, Menispermaceae, Tiliaceae, Bignoniaceae, and Menispermaceae. According to Penz and DeVries the ancestral diet of larval Satyrinae is Poaceae or other monocots. Many morphos have switched to dicots on several occasions during their evolutionary history, but
