Freshwater Macroinvertebrate ID

There is no “field guide” that can get you to genus for any of these taxa. Most require microscopic examination and many require dissection and/or slide mounting (especially chironomids) for genus/species id.

Merritt et al. (2018) can get you to genus for most taxa in North America, but it can be unwieldy and still requires a lot of time and effort to maybe get an id for someone not trained. There are few comprehensive resources for the taxa you list (see Dragonfly Nymphs of North America). While there are many taxon- and region-specific works that can be used for ids, often they are so scattered it is not easy to recommend a single source for one location. For a lot of taxa it may require combining many different sources from the primary literature or it may not be possible to id to species if differences among immature stages are not known.

I would advise against using macroinvertebrates.org since it is just a very superficial overview and excludes most genera.
