Two pair of Emerald Glass Frogs (Centrolenidae: Centrolenella prosoblepon), in amplexis, readying themselves to release their gamates.
On some of the images, you can see a small blue-ish spike that is anterior to the male’s forelegs. This spike is diagnostic of the genus and is used by males to compete for mates.
Hemidactylus frenatus
Jessie Knowlton, one of the mentors of NAPIRE, had a keen eye for sleeping Norops polylepis.
Another katydid (tettigoniidae)… perhaps the last of a little while. We discovered this individual resting in this position; I wonder if it’s listening for calls?
At least I think this is another long-horned orthopteran. There are several families in the tropics of Orthopterans that I don’t know, so it could be something entirely different. This individual has a short-horned grasshopper appearance (Acrididae), but extremely long antennae, which is a characteristic of the tettigonids (i.e., katydids). The tympana location differs between the two families too: it should be on the tibia of the fore-legs in tettigonids as seen here.
Juvenile female leaf-mimicking katydid (Tettigoniidae). Females have the large, sword-like, ovipositor at the end of their abdomen, and adults have full wings that cover the entire body.
I also ran into this, which I took in another part of Costa Rica a few years ago.
Found another katydid (Tettigoniidae) with spermatophores/nuptial gifts present, as I mentioned observing here!
The little white bubbles at the tip of this female’s abdomen (about halfway down the length of the wings; there are two, but only one is visible on this shot), can contain various amounts carbohydrates and proteins as a gift from a mate along with sperm.
