IDENTIFICATION
Size: A medium sized burrowing frog measuring 2 to 3 inches
in length.
Color: The dorsum is light brown to black with a yellowish lyre
shaped marking. The venter is translucent white.
Spadefoots have a distinct black “spade” on each hind
foot to aid in the burrowing process.
Behavior: Fossorial spending the majority of their time
underground. Active at night mostly during rain events.
When handled they may vocalize to express alarm and
distress. When ingestion by predators is imminent they
puff up and excrete a distasteful toxin from their parotoid
glands located just behind their eyes, often causing the
would-be predator to release them.
Habitat: Spadefoots are uncommon only occurring at a few
eastern Connecticut sites that are characterized by sandy
and often scarified soils mixed with herbaceous, shrub
and forested habitats. Temporary rain filled pools are
used for egg deposition and rapid larval development.
Few breeding locations are known in Connecticut.
