Photograph taken 23-Sep-06.

In the center of Larkin Lake, a hole has been scooped out, and resulting hole contained some very green water. There were pollywogs in the water, some of which had front and back legs. But many had died. The yellow jackets were swarming to eat the dead pollywogs.

Later, having returned home, I reviewed the collections of frogs at the Museum of Vertebrate Zoology (MVZ). There are four species of frogs that have been collected in Mono County. They are:

  1. Great Basin Spadefoot Toad (Spea intermontana).
  2. Mountain Leopard Frog (Rana pipiens).
  3. Mountain Yellow-legged Frog (Rana muscosa).
  4. Pacific Tree Frog (Pseudacris regilla).
Of the four species, it seems more likely that the species I found at Larkin Lake is the Great Basin Spadefoot Toad. The true frogs (Rana sp.) and the tree frog (Pseudacris regilla) have been collected in the Sierra Nevada of Mono County, or at the Sierra front, but not out in the Great Basin of Mono County.
