Collection localities of D. nigrospiracula individuals and necrotic cactus tissues (Fig. S01); rarefaction and sample completeness curves for each sample (Fig. S02); paired comparisons of the average abundances for individual OTUs (Fig. S03); principal coordinate analyses of the gut microbiota structure (Fig. S04); UPGMA dendrograms showing the beta-diversity relationships among the microbiota of individual D. nigrospiracula and cactus tissues (Fig. S05); pairwise correlations (Kendall’s tau) between the top 30 most-abundant OTUs present in D. nigrospiracula individuals (Fig. S06); pairwise sequence distances between the top 40 most-abundant OTUs present in cactophilic D. nigrospiracula and mycophagous Drosophila species (Fig. S07).
