Distribution

While I have county distribution data for the spiders of Minnesota, I currently do not have the infrastructure to produce a user-friendly map-like interface that will enable the public to readily determine where in the state each species can be found.  Below is a table showing the number of spider species currently recorded for each county (last updated 17 May 2025).  It is difficult to predict how many species may be found in each county, but I expect at least 400 species per county (and perhaps as many as 600 species).  You can see how much discovery has yet to happen!

You can also help with completing known distributions by submitting photographs to the Spiders of Minnesota Project on iNaturalist.
