The number of freshwater macroinvertebrate taxa occurring in eastern North America is much greater than the number imaged and annotated in this project.
How were the project’s taxa chosen?
Why are annotations provided sometimes for a genus, sometimes for less-refined levels of taxonomy such as a family or an order? What criteria were used to decide the amount of detail provided in the annotations?
At a minimum, the level of annotation provided for each taxon is the level needed to distinguish it from other taxa imaged in this project. At the level of order and family, our annotations will often distinguish the taxon from all other North American taxa, but for families with multiple genera we did not attempt to annotate genera sufficiently to distinguish them from other North American genera that are not imaged.
