Caterpillars are a popular prey item for birds, mammals and insects and are widely used for predator-prey interaction studies. Pandora & Achemon Sphinx moth larvae found in MA have multiple color morphs: green, red, orange and brown. Yet, they are assumed to be palatable to predators. The larvae have conspicuous splotch markings on their sides but the functionality of these markings have not been explored. I will utilize artificial prey to see if coloration & patterning affect predation risk.
