Northern Cricket Frog (Acris crepitans)
Order: Anura; Family: Hylidae; Genus: Acris; Species: A. crepitans. While in the treefrog family Hylidae, this genus is terrestrial and semi-aquatic rather than arboreal.
Species
Northern Cricket Frog (Acris crepitans)
Family
Order: Anura; Family: Hylidae; Genus: Acris; Species: A. crepitans. While in the treefrog family Hylidae, this genus is terrestrial and semi-aquatic rather than arboreal.
Size
Adult SVL typically ranges from 16 to 38 mm (0.6 to 1.5 inches). Females are generally slightly larger than males. Metamorphs are tiny, often less than 15 mm long.
Conservation
IUCN status: Least Concern. However, many northern populations in the Midwest and Northeast have experienced dramatic, unexplained declines and are state-listed as Endangered or Threatened in places like New York and Wisconsin.
Description
The Northern Cricket Frog is a master of camouflage, blending perfectly with the mud and leaf litter of the water's edge. Though it is a member of the treefrog family, it has traded the canopy for the shoreline, possessing powerful legs that make it one of the most athletic leapers in the amphibian world. Watching one navigate a pond edge is a lesson in agility and speed.
Key Features
Warty skin, dark triangle between the eyes, small size, and a metallic 'clicking' call.
Physical Description
A small, robust-bodied frog with a somewhat pointed snout. The limbs are relatively long for its size, designed for powerful leaping. It lacks the large, adhesive toe pads typical of other hylids; instead, it has small discs and significant webbing on the hind feet. The eyes are moderately large with horizontal pupils.
Skin Texture & Coloration
The skin is distinctly granular or 'warty,' though not to the level of true toads. Coloration is highly variable, ranging from gray and brown to green. Often features a dark, V-shaped or triangular mark between the eyes and a ragged dark stripe on the thigh. The dorsal pattern usually includes irregular blotches or a spinal stripe.
Distinguishing Features
A dark triangular patch between the eyes is the hallmark of the genus Acris. It is distinguished from the Southern Cricket Frog (Acris gryllus) by its shorter legs (the heel does not reach the snout when pressed forward) and more extensive webbing on the fourth toe of the hind foot.
Habitat
Found near permanent water sources such as ponds, lake margins, slow-moving streams, and marshes. They prefer muddy or gravelly shorelines with abundant vegetation for cover but are rarely found climbing high into trees.
Geographic Range
Native to the central and eastern United States, ranging from the Northeast (New York) south to the Gulf Coast and west through the Great Plains to Texas and New Mexico.
Behavior
Diurnal and highly active during the day. Known for its incredible jumping ability; it can leap over 3 feet in a single bound to escape predators. They often jump into water and immediately swim back to the shore to hide in mud or vegetation.
Diet & Feeding
An active insectivore that consumes a wide variety of small invertebrates, including flies, beetles, ants, spiders, and midges. They hunt by leaping at prey or using their sticky tongue.
Reproduction
Breeding occurs from late spring through summer (April to August). Males call from the water's edge. Eggs are laid singly or in small clusters attached to submerged plants. Amplexus is axillary.
Vocalizations
The call is a series of sharp, metallic clicks, often compared to the sound of two pebbles or marbles being struck together: 'glick-glick-glick.' The tempo starts slow and increases in speed.
Life Cycle
Eggs hatch into tadpoles within a few days. The tadpole stage lasts 5 to 10 weeks depending on water temperature. Tadpoles typically have a diagnostic black-tipped tail. Most individuals live only 1 to 2 years in the wild.
Conservation Status
IUCN status: Least Concern. However, many northern populations in the Midwest and Northeast have experienced dramatic, unexplained declines and are state-listed as Endangered or Threatened in places like New York and Wisconsin.
Toxicity & Defense
Not toxic to humans. Primarily relies on cryptic coloration (camouflage) and explosive jumping to avoid predators. When caught, they may secrete a mild mucus that is unpalatable to some smaller predators.
Ecological Role
Serves as both a significant predator of small insects and a vital food source for larger animals like garter snakes, herons, and larger frogs (like Bullfrogs).
Similar Species
Southern Cricket Frog (Acris gryllus) has longer legs and less webbing. Spring Peepers (Pseudacris crucifer) have a characteristic 'X' mark on the back and smoother skin.
Observation Tips
Walk slowly along the muddy edges of ponds on sunny afternoons in June or July. You will often see them jump away from your footsteps before you see them sitting still. Listen for the 'clicking' chorus at dusk.
Handling & Safety
Safe to handle, but their skin is sensitive. Always have wet hands free of soaps or repellents. Because they are so small and agile, they are easily injured if squeezed or dropped; observation without handling is preferred.
Seasonal Activity
Active from early spring until late autumn. They overwinter on land, often burrowing under leaf litter or in cracks in the soil near the water's edge.
Cultural Significance
Often used as a 'sentinel' or indicator species for wetland health due to their sensitivity to water pollutants and habitat fragmentation.
Interesting Facts
Despite their small size, they are one of the most abundant vertebrates in many wetland ecosystems. They have one of the highest jump-to-body-length ratios of any vertebrate.
