Baja California Treefrog (Pseudacris hypochondriaca)
Amphibians Around Las Vegas, Wildlife Around Las Vegas
Pacific Treefrog [Pacific Chorus Frog] (Pseudacris regilla)
Typical adult, green color morph

General Description: Baja California Treefrogs (Pseudacris hypochondriaca) are small frogs with suction cups on the toes and a dark line through the eye (facial mask) that ends at about the shoulder. These frogs come in green and brown, but the eyeline is consistent.

Taxonomy: Order Frogs and Toads (Anura); Family Treefrogs (Hylidae). Formerly Pacific Treefrog (Hyla regilla), then Pacific Treefrog (Pseudacris regilla). Now, the Baja California Treefrog (Pseudacris hypochondriaca) has been split from the Northern Pacific Treefrog (Pseudacris regilla). Around Las Vegas, we have the northern subspecies of the Baja species: Northern Baja California Treefrog (Pseudacris hypochondriaca hypochondriaca), which may, itself, be a distinct species. Much scientific work remains to be done to sort out the taxonomy of these little frogs.

Diet: Mostly flying insects.

Habitat: Wet areas, including streams, ponds, and marshes. Usually found near the ground, in and around emergent vegetation.

Comments:

Pacific Treefrog [Pacific Chorus Frog] (Pseudacris regilla)

Froglet. Notice the four fully developed legs, including toepads and the complete tail. As it grows, this froglet will absorb its tail, using the nutrients and tissue as it grows. This little froglet was captured on what might have been its first attempt to leave the water; hopefully it learned from the incident.
