Description: The crawfish frog grows from 2.2 to 3.0 inches in length. It ranges from yellow to brown in color, with a white ventral surface. The numerous dark brown spots on its back each has a light-colored ring around it. It has a distinct skin fold on either side of its back, which are much more pronounced in males than females, and a relatively small tympanum.
Habitat: Grasslands, prairies, and woodlands are areas where R. areolata is most likely to be encountered. However, it is hard to find R. areolata because it lives underground most of the year in old, vacant burrows of other animals. The opening of these burrows are about 76.2 mm wide and are usually covered with grass. However, during the mating season, L. areolata resides near river floodplains, ponds, and lakes.
Range: Range extends from northern and central Mississippi, northern Louisiana, and eastern Texas north through eastern Oklahoma, Arkansas, western Tennessee, and western Kentucky to eastern Kansas, southern Iowa (at least formerly), southern Illinois, and Indiana.
Diet: Crawfish frogs feed opportunistically on insects and other small invertebrates that pass by their burrow.
Reproduction: The crawfish frog breeds following mild, rainy weather in mid-March throughout most of its range (breeding occurs much earlier in the southern portion of its distribution). During this time, males seek out ephemeral ponds and wetlands that lack fish and begin calling. The low-frequency call may carry over a mile, drawing females in from the surrounding area. Once the females arrive, amplexus takes place and the females deposit up to 7,000 eggs at a time in large, globular masses. The eggs hatch in about 12 days, and the tadpoles complete metamorphosis into froglets within three or four months. The newly metamorphosed juvenile frogs must quickly find a crayfish burrow to occupy to avoid predation. Crawfish frogs become sexually mature at two to three years of age and may live up to seven years or more in the wild.
Status: The crawfish frog is listed as near threatened by the IUCN Red List of Threatened Species, and is listed as endangered in Iowa (where it has likely been extirpated) and Indiana. Habitat loss is the biggest threat to this species, though disease (chytridiomycosis) and competitive pressure from other anurans have also been identified as potential stresses.
