Digital Macroinvertebrate Reference Collection Now Available

The USGS Fort Collins Science Center's in collaboration with the Colorado Water Science Center has released a digital macroinvertebrate reference collection for aiding in specimen verification. Images are open-source and public domain, so they are available for use in presentations and publications without permission.

The current iteration is dominated by insects (and western genera) identified at the genus level but we are expanding the collection to non-insects and greater geographic coverage over the coming months and years. The collection also includes some images of adult and pupal life stages.

Please share this information with colleagues, students, etc. in the benthic business and let Bob Zuellig,, know if you have any comments, etc. Also, please let him know if you are interested in contributing specimens or images.

Images are available at
