Giant water bug (Belostomatidae: Lethocerus medius).

Donation of USGS NAWQA Macroinvertebrate Collection

In early 2012, the University of Minnesota Insect Collection (UMSP) acquired a large portion of the United States Geological Survey National Water-Quality Assessment Program (USGS-NAWQA) aquatic macroinvertebrate collection for curation and permanent retention. The collection was donated to the University of Minnesota by the USGS National Water Quality Laboratory (NWQL) in Denver, CO to ensure its continued existence and to make it available for further research, as it was slated for disposal in spite of its historical and contemporary importance and its excellent curatorial condition, diversity of taxa, and geographic coverage.

The collection represents sampling efforts beginning in 1993 across the USA, and includes some 225,000 vials and more than 2.2 million specimens. Most material is identified at least to genus, with a large portion identified to species.

Insect material is currently undergoing taxonomic organization and integration into the UMSP collection. Specimen vials are being barcoded and their associated data are being uploaded into Specify 6. Non-insect material, such as annelids, mollusks, and gastropods, are being donated to the Bell Museum’s Mollusks & Crustaceans collection.

This material is based upon work supported by the National Science Foundation under grant numbers DBI-1132188 and CSBR-1561390.
