  1. Data were analyzed with multi-factor ANOVA to determine the effect of cellular compartment (host vs. LBs) and time for each WEs species (*p < 0.05, **p < 0.005, ***p < 0.001), and letters adjacent to values (concentration ± SD) represent statistically significant differences across sampling times and compartment within a WE species, as determined by Tukey’s post hoc tests (p < 0.05). The concentrations of all four lipid species were higher in LBs than host gastrodermal cells at all four sampling times (p < 0.05; excepting C18:1/R′ = C16 at sunrise), as well as when data were pooled over time for each of the four lipid species (p < 0.05). “—” = not detected.
