Pacific Treefrog [Pacific Chorus Frog] (Pseudacris regilla)
Typical adult, dark color morph

General Description: Northern Pacific Treefrog (Pseudacris regilla) 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), and now Northern Pacific Treefrog (Pseudacris regilla) after the Baja California Treefrog (Pseudacris hypochondriaca) was split off. Much scientific work remains to be done to sort out the taxonomy of these little frogs.
