This species is found in North America, ranging from Ontario and Quebec south through Maine and Connecticut to Florida, west to Texas and Oklahoma, and north to Minnesota. The wingspan of adult Catocala similis measures between 35 and 45 mm. Adults are active on wing from May to July, with the timing varying based on location.
