About Acris blanchardi Harper, 1947
Blanchard's cricket frogs (Acris blanchardi Harper, 1947) are a species of aquatic tree frog native to North America. They have warty skin that is most often brown, gray, tan, or olive green, with darker colored bands on their legs. Their skin is heavily vascularized, which lets substances enter their bodies quickly and increases their susceptibility to disease. For this reason, handling these frogs with bare hands is not recommended. A dark triangular mark between the eyes is commonly seen, and this mark can be used to easily identify the species. The backs of some individuals may display a variety of colors, most often dark red, orange, or light green; combinations of these colors occur more rarely. These are small frogs, with an average adult length of 0.6 inches (1.5 cm). Blanchard's cricket frogs hibernate during cold months, starting hibernation in late October and emerging in late March or early April. Their breeding season runs from mid-May to mid-July. Females lay eggs either singly or in small clusters, and tadpoles hatch in late summer. Breeding males produce a distinctive metallic clicking call unique to this species. The species is named after Frank N. Blanchard, a well-known American herpetologist. These frogs are most often found in slow-moving or stagnant bodies of water, including streams and wetlands, where they reproduce. Very few individuals survive until their second breeding season. If a breeding season is not productive, local populations can decline. Blanchard's cricket frogs range from northeastern Mexico north to South Dakota, and east to Ohio and West Virginia. The southeastern edge of their range generally follows the Ohio River and the Mississippi River, and the species has been recorded in parts of western Mississippi.
