The southern cricket frog or southeastern cricket frog (Acris gryllus) is a small hylid frog native to the Southeastern United States. It is very similar in appearance and habits to the northern cricket frog, Acris crepitans, and was considered formerly conspecific (Dickerson 1906). The scientific name Acris is from the Greek word for locust, and the species name gryllus is Latin for cricket (Georgia Wildlife).
At 0.75–1.5 inches (16–32 mm) in length, Acris gryllus is even smaller than A. crepitans. Other characters that differentiate the southern species are: More pointed snout--A. crepitans more blunt. Hind leg is more than half length of the body when folded—that of A. crepitans is less than one half body length. When rear leg is extended forward, the heel of A. gryllus usually reaches beyond the snout—does not reach snout in A. crepitans.
A. gryllus can jump longer distances than A. crepitans. A. gryllus has a sharply defined black stripe on the back of the thigh--A. crepitans has a ragged stripe. Webbing on rear feet of A. gryllus is sparse, more extensive in A. crepitans.
There is evidence that the color of the vertebral stripe on southern cricket frogs can... Wikipedia →

Rare
Under 5% of wildlife watchers report a Southern Cricket Frog sighting in Miami on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 12th most-seen of the 12 amphibians we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Southern Cricket Frog in Miami on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Southern Cricket Frog sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Miami, in our data
Miami is the only city on Wallace's Line with enough records to rate Southern Cricket Frog sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Southern Cricket Frog is recorded against all the amphibians logged in Miami (7 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
