In observing how Phaneroptera brevi katydids pick and choose flowers to eat (such as Sphagneticola trilobata), researchers at the National University of Singapore found that area and biomass of rays (the broader “petals” of the flowers) both correlated positively with palatability for the katydids. Understanding insect florivory habits could have applications in agriculture or even weed control. (Photo credit: Ming Kai Tan)
