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.

Not green, but red
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!
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.
