Life History, Abundance, Activity, and Special Behaviors
Eggs are laid in January, in a slimy mass, hidden in the leaf litter. At eclosion time the slimy mass liquefies and the tadpoles develop in it. One nest contained 45 eggs and 9 embryos in a different stage of development. A second nest contained 28 eggs.
