Hygrophorus russula, commonly known as the pinkmottle woodwax, is a fungus native to North America.

The spring peeper, or Hyla crucifer, is a tiny climbing tree frog, about an inch long.

The Spring peeper (Hyla crucifer) ranges throughout Great Lakes Basin.

Other frogs of North Carolina include spring peepers, Pseudacris crucifer or Hyla crucifer.

The two groups were (i) Ambystoma maculatum, Hyla crucifer, and Rana sylvatica and (ii) Rana clamitans, Rana catesbeiana, and Rana palustris.

Using the haematocrit centrifuge technique, four species of trypanosomes were detected in the blood of 46 of 275 hylids (Pseudacris triserita, Hyla crucifer, Hyla versicolor, Hyla chrysocelis, and Hyla avivoca) from eastern North America.

Diel activity patterns in the breeding migrations of four winter-breeding anurans (Hyla crucifer, Pseudacris nigrita, Pseudacris ornata, and Rana utricularia) were examined at a breeding pond in South Carolina, U.S.A., using a terrestrial drift fence with pitfall traps.
