Northern Cricket Frog (Acris crepitans)
Order: Anura; Family: Hylidae (Tree Frogs); Genus: Acris; Species: A. crepitans. Despite being in the tree frog family, these are terrestrial/aquatic and lack large toe pads.
Species
Northern Cricket Frog (Acris crepitans)
Family
Order: Anura; Family: Hylidae (Tree Frogs); Genus: Acris; Species: A. crepitans. Despite being in the tree frog family, these are terrestrial/aquatic and lack large toe pads.
Size
A very small species; adults typically range from 16 to 38 mm (0.6 to 1.5 inches) in snout-to-vent length (SVL). Females are generally slightly larger than males.
Conservation
Listed as Least Concern globally by the IUCN, but populations have seen dramatic and mysterious declines in the northern and western parts of their range, leading to state-level 'Endangered' status in some areas.
Description
A tiny powerhouse of the wetlands, the Northern Cricket Frog may look like a common pebble until it erupts into a massive leap. Its warty skin and cryptic colors make it an expert at blending into mud banks and leaf litter.
Key Features
Dark triangle between the eyes, warty/granular skin, lack of large toe pads, and a 'marbles clicking' vocalization.
Physical Description
Small, robust frog with a somewhat flattened body; pointed snout and large hind legs designed for jumping. The eyes are prominent and lateral, with a dark 'mask' or stripe through the eye. Toe pads are present but very small and inconspicuous compared to other Hylids.
Skin Texture & Coloration
Skin is distinctly granular and warty, giving it a rough appearance. Coloration is highly variable, ranging from gray, brown, to green. Often features a bright green or reddish-brown stripe down the center of the back and a characteristic dark triangular mark between the eyes.
Distinguishing Features
The most diagnostic feature is the dark triangle between the eyes. Also noted for the 'ragged' white stripe on the jaw and dark, longitudinal stripes on the back of the thighs. Hylid-like body but without expanded toe pads.
Habitat
Found near the edges of permanent water sources like slow-moving streams, ponds, and marshy lake edges. They prefer sunny areas with abundant vegetation or mud flats rather than deep forest.
Geographic Range
Native to the Central and Eastern United States, ranging from the Northeast through the Great Plains to the south. Several subspecies exist, such as the Eastern and Blanchard's cricket frogs.
Behavior
Extremely active and agile; they are famous for their powerful jumps, which can cover over 3 feet in a single leap to escape predators. They are primarily diurnal or crepuscular, though they call at night.
Diet & Feeding
Generalist insectivores. They consume a wide variety of small invertebrates including ants, beetles, flies, and spiders. They use a sit-and-wait strategy combined with active lunges.
Reproduction
Breeding occurs from late spring through mid-summer. Males call from the water's edge. Eggs are laid singly or in small clusters attached to submerged vegetation. Mating is via axillary amplexus.
Vocalizations
The call is one of the most distinctive in North America: a series of sharp, metallic clicks resembling two marbles or pebbles being hit together rapidly ('gick-gick-gick'). Starts slow and accelerates.
Life Cycle
Eggs hatch into tadpoles within a few days. The larval stage lasts 5 to 10 weeks depending on water temperature. Tadpoles are notable for having black-tipped tails. Metamorphs are tiny, often appearing in late summer.
Conservation Status
Listed as Least Concern globally by the IUCN, but populations have seen dramatic and mysterious declines in the northern and western parts of their range, leading to state-level 'Endangered' status in some areas.
Toxicity & Defense
Non-toxic to humans. Their primary defense is their невероятно camouflage and their ability to leap long distances into water to avoid capture. They may also secrete mild mucus to deter small predators.
Ecological Role
Serves as an important mid-level consumer in the food web, controlling insect populations while providing a high-protein food source for larger frogs, snakes, and wading birds.
Similar Species
Southern Cricket Frog (Acris gryllus), which has a more pointed snout and shorter legs; Western Chorus Frog (Pseudacris triseriata), which is smoother with distinct stripes.
Observation Tips
Listen for the sound of clicking marbles near sunny pond edges in June or July. Look for small movements on mud flats; they are easier to hear than to see due to their camouflage.
Handling & Safety
Safe to handle, but like all amphibians, their skin is permeable. Wash hands before and after handling, and ensure your hands are wet to protect their mucus layer. Avoid using bug spray or lotion before touching them.
Seasonal Activity
Active from early spring through autumn. They hibernate (brumate) underwater or in moist burrows near water during the winter months, emerging once temperatures consistently stay above freezing.
Cultural Significance
Commonly used as a 'bio-indicator' for water quality in the American Midwest. Their presence often signals a healthy, unpolluted aquatic ecosystem.
Interesting Facts
Despite being members of the tree frog family (Hylidae), they have lost the ability to climb well and are almost exclusively ground-dwelling. They are among the longest jumpers for their size in the world.
