Figure 4

Ternary plot showing preference of 21 neonate sibling groups for leaf tissues of each host species (one choice trial per group, groups comprised of 3–6 individuals). Colors delineate instances in which more than half of the total leaf area eaten was that species. There are 2 overlapping points in each corner of the plot where neonates fed only on that species. The ‘x’ indicates population mean. Inset: when given the choice between bracts or leaves from the same stem of either Castilleja species, neonate larvae strongly preferred bracts. Points show mean proportion of leaf area eaten by each sibling group; brackets are ± 1 SEM.
