Correlation between biomass and data volume. The sequence volume for each given taxon was measured by number of base pairs. The corresponding biomass was estimated based on the body-length. Hollow circles represents the taxa with a single individual, while solid circles represents the taxa with multiple individuals. Number of individuals in the corresponding MOTU is also labeled on the solid circle. Small taxa were typically sequenced at lower sequencing volumes. But those represented by multiple individuals had higher sequencing volume. The increase of sensitivity for these small insects was likely a consequence of the increased total biomass for the given species.
