The captions for Figs 6 and 7 are incorrectly switched. The images appear in the correct order. Please see the corrected captions here.

Fig 6

Some players in the tritrophic system—upper left, caterpillar of the orange-barred sulfur butterfly, Phoebis philea, on Senna chapmanii; upper right, pupa (chrysalis) of P. sennae; lower left, adult P. sennae; lower right: caterpillar studded with sucking flies (virus transmitters?).

When viruses are involved, the pupae do not hatch, but instead turn various colors.

Fig 7

Predators on Senna chapmannii plants—upper left, Polistes major wasp with Phoebis philea caterpillar; upper right, Polistes wasp damage to Phoebis sennae chrysalis; lower right, coccinelid Brachiacantha decora adult at extrafloral nectary; lower left, thomisid spider Misumenoides formosipes ready for prey.
