λ/4 Retarder Film Measurement from: Polarization of foliar reflectance – novel host plant cue for insect herbivores

Adam Blake, Matthew Go, Gina Hahn, Hayley Grey, Samuel Couture & Gerhard Gries
Insect herbivores exploit plant cues to discern host and non-host plants. Studies of visual plant cues have focused on color despite the inherent polarization sensitivity of insect photoreceptors and the information carried by polarization of foliar reflectance, most notably the degree of linear polarization (DoLP; 0-100%). The DoLP of foliar reflection was hypothesized to be a host plant cue for insects but was never experimentally tested. Here we show that cabbage white butterflies, Pieris rapae...
