About Catocala praeclara Grote & Robinson, 1866
Catocala praeclara, commonly known as the praeclara underwing, is a moth species belonging to the family Erebidae. This species was first formally described by Augustus Radcliffe Grote and Coleman Townsend Robinson in 1866. It is distributed across North America, ranging from Nova Scotia west to southeastern Alberta, and extending south to Florida and Kansas. The wingspan of adult praeclara underwings measures between 38 and 50 mm. Depending on location, adults are active from August to September, and produce one generation per year. The larvae of Catocala praeclara feed on plants from the genera Amelanchier, Crataegus, and Photinia; recorded host species within these genera include Crataegus calpodendron, Photinia prunifolia, and Photinia melanocarpa.
