Sampling information.
Fig 1.
Venn diagram of the gut bacterial communities features in different feeding habits.
Shared features were shown in core.
Table 2.
Alpha diversity analysis of the gut bacterial communities.
Fig 2.
Bacterial communities clustered by using principal component analysis (PCA).
Fig 3.
Bacterial communities clustered by using principal coordinates analysis (PCoA) based on the weighted unifrac distance.
Eigenvalues of PCoA1 and PCoA2 are shown in parentheses. Samples were colored according to insects feeding habits (A) and insects taxonomy on family level (B).
Fig 4.
Bacterial community composition across samples at (A) the phylum and (B) the genus levels.
Taxa without a top 30 abundant are indicated as others.

Top 4 abundance gut bacteria at the phyla and genera levels of samples with different feeding habits.
Fig 5.
A clustered heatmap using the corresponding dendrogram illustrating the top 30 mean abundances of the bacterial community taxa assigned to phyla (A) and genera (B) level.
The color scale of higher (red) and lower (blue) show the relative abundances of bacterial communities.

Fig 7.
Heat map illustrating the common and endemic bacteria community abundances according to insects feeding habits (A) and insects taxonomy (B) at the genus level.
The color scale of higher (red) and zero (blue) show the relative abundances of bacterial communities.
