With much help, I’ve filled a new set of enclosures for another competition experiment. This time, I have varied both initial density (8, 16 and 32 plants) and proportion of the two species. I’ve also repeated decomposition bundles within the enclosures, although the picture here doesn’t include them. The density manipulation can be seen with this photograph, though.
This dragonfly is now much more abundant than the green one. It’d be interesting to see if they share similar food sources and temporally separate emergence to avoid competition.
What evolutionary forces drive dragonfly color?
Hesperidae (skipper butterflies) are the Thalia herbivores, according to Tim, an IRES student currently studying termite behavior at Palo Verde.
I’ve observed both swallows (barn swallows + another I’ve yet to identify) and fly catchers (Great kiskadee and maybe another smaller species) capturing the hesperids.

One of two species of floating aquatic ferns at Palo Verde, the leaves of S. minima are extremely small and are covered with dividing setae.
Now, who knows the family of the bug surveying the Salvinia?
What is this goop? It feels like Jell-O.

are this color according to my camera and your laptop screen.
I think this is the same species that stung me in the lip. They construct a ball-like hive and the individuals are of similar appearance. In the photograph below, one of the workers is about to place another ‘brick’.
