The Michigan Technological University Insect Collection features over 10,000 specimens primarily from under-sampled areas of Michigan's western Upper Peninsula, filling distribution gaps for the region. Housed in MTU's College of Forest Resources and Environmental Science, the collection dates to the 1930s and has been used as a repository for both faculty and students since its inception. Michigan's Upper Peninsula is a heavily forested transitional zone between boreal and northern hardwood ecosystems, featuring unique habitat types and associated arthropod communities. This expanding collection features a large portion of specimens collected in the 1960s through the 1970s, as well as the early 2000s to the present day. Twenty-three insect orders are represented, with strengths in Coleoptera, Hemiptera, and Lepidoptera.
