Travelling caterpillars
The caterpillars below have likely consumed all available resources in one place and are moving together to find more food or pupate. The video isn’t well focused, but it does illustrate the pile of caterpillars moving as one ‘slug’ across the stair.
An overlook at Las Cruces
A small group of us hiked to some newly acquired abandon pasture at the Las Cruces Biological Station that sits at the highest elevation of the reserve–1400 m.

Emerald glass frogs in amplexis
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.
