Figure S2. Correlation between mouthpart conduit and limiting substrate pore size radii for tested species. from Mouthpart conduit sizes of fluid-feeding insects determine the ability to feed from pores LehnertMatthew S. BennettAndrew ReiterKristen E. GerardPatrick D. WeiQi-Huo BylerMiranda YanHuan LeeWah-Keat 2017 The left graph shows insects in the prefed treatment and the right graph shows the unfed treatment. The graphs illustrate the nearly linear relationship between pore size radius ( for prefed insects. ;Forewing length (FWL) and food canal diameter (µm) measurements (mean±s.e.m.) of studied butterfly and fly species (n=5) with results of a paired t-test (P-values) comparing distal and proximal mouthparts measurements. ;Results of studied butterfly and fly species (n=5 per species), including percentage that fed on nanoparticle solution from filters of different pore sizes, percentage that salivated and fed, and limiting substrate pore sizes (calculated threshold of 50% that fed). ;Results of feeding experiments of studied butterfly and fly species (n=5 per species), including the percentage that fed on nanoparticle solution from filters of different pore sizes and limiting substrate pore sizes (calculated threshold of 50% that fed).
