Poa annua or Annual Bluegrass is an abundant weed in disturbed moist areas and lawns. It is native to Europe but now distributed more or less worldwide. This grass flowers normally in the winter and spring but can bloom continuously as long as enough water is available. It belongs to the Poaceae (Gramineae) or grass family, which is the most economically significant plant family, since it includes wheat, rice, maize (corn), sugar cane, millet and many others. The Fiery Skipper butterfly uses plants in the Poaceae as host plants.
