It turned too cool for the wasps to be out on the callas this weekend, but
had plenty of small flies. The instant one lands on the spathe, the frogs'
eyes open and zap!- lunch. Then they close their eyes and become virtually
invisible again. They either can't detect the flies landing on the spadix
behind them or just ignore them til another one lands directly in front of
them on the spathe.
I have some aethiopica 'Kiwi Blush' getting ready to flower. It will be
interesting to see if they can match this spathe color, or just stay green
parked on the leaves.

This discussion about the tiny frog inhabiting the bloom of the native
African Zantedescia sps. ("Arum lily") brings to mind something that I
know of in Trinidad, W.I.
Many years ago I was trying to collect one of the rarest of the many frog
species we have on Trinidad, Flectonotus (Gastrotheca) fitzgeraldi, the
Trinidad Marsupial frog, called that because it incubates its few large
eggs in a 'marsupium' or pouch/groove along its dorsum. I was told
that the way to see this little (finger-joint sized) frog was near the Bat
caves near Tamana in Central Trinidad`s jungle. One of my Mentors, Dr.
Jack Price, had collected it there when working w/ Dr. Jake Kenny on the
frogs of Trinidad and Tobago. HERE COMES THE AROID CONNECTION!! Jack
told me that it lived in the basal leaf-sheaths of a giant Xanthosoma sp.
(Xanthiosoma cf. undipes), known locally as 'wild tannia' that grew
there. I made a trip and climb to these caves where we discovered this
plant was abundant near the entrances to these smelly bat caves, and after
much chopping and searching we did see this little tree-frog slipping
effortlessly in and out of the sheaths, NOT easy to catch! I wonder if
perhaps this plant , besides providing a moist/wet safe haven in its basal
leaf sheaths for this tiny frog, might also provide a higher temp. than
that of the surrounding air?? I was also thinking that perhaps the
higher temperature produced within the spathe of Zanthedescia would be
advantagous to a tiny frog, plus of course the insects provided as food
and attracted to the scent of the bloom at anthesis???? All food for
thought and further research!
