Dots on the above map (obtained from transformed GPS coordinates) show the relative position of flowering plants.
Positions don't map exactly onto the photo because of imprecision and inaccuracies in GPS measurements, plus the angle of the panoramic photo.

A female moth "cheating" by ovipositing in a developing fruit. We are uncertain whether this is: (1) a labile behavior, (2) a behavioral polymorphism within T. maculata populations, or (3) a case of incipient speciation.
