From a few years ago, in La Selva.
A common litter-dwelling frog, Craugastor megacephalus has recently been moved to a new family, Craugastoridae (formerly Leptodactylidae). It’s cranial ridges and warty-appearing skin are generally thought of as toad characteristics, but this rain frog lacks large, poison-secreting, parotiod glands behind the eyes.
This individual was caught along side the Norops humilis in La Selva.
In early January, the Canta Rana wetland in La Selva was alive with a tiny, yellow hylid. Since I didn’t take proper pictures for identification, my best guess is Hyla phlybodes; it’s supposedly common both in the region and the reserve itself, and can be frequently heard calling around that time of year.
The other magnificent frog at the wetland you’ve already seen.
The group Bernald and I led in La Selva collected aquatic insects from several stream sites that varied in total discharge and water velocity (essentially a riffle-pool macroinvertebrate community study). One of the coolest finds was this aquatic Lepidopteran larva in the genus Petrophila (Pyralidae), particularly since I had never seen any aquatic insect larva in this insect Order. Interestingly, many aquatic lepidopteran larva are shredders/herbivores of Typha.
