Results from gut metabarcoding of L. mimadelfi and nine other cockroach taxa. Numeric values are total read count (top) or number of operational taxonomic units (OTUs) of food items identified in the gut (bottom). Cells are colored relative to the cell value, with deep purple values indicating major gut components, intermediate shades indicating minor gut components, and white indicating absence. Cockroach taxa are lumped by clade so numbers are roughly comparable, but note that results from multiple primers are also lumped here, which adds a great deal of variability to the results. Food items are categorized by broad taxonomic groups (from left to right: monocots, eudicots, fungi, metazoans, green algae) and then subcategorized by ecological groupings. Ecological groupings are meant to be interpretable for diet characterization. For example, Neoblattellini spp. show strong signal as algae scrapers, and Nahublattella sp. is partially carnivorous (likely a detritivorous omnivore). L. mimadelfi primarily feeds on lignocellulytic fungi, and does so more than any other species surveyed.
