Help researchers by recording where Spiders live in Utah with iNaturalist. 

  • Take a walk outside to look for spiders, and photograph ones you come across. Useful spider observations added to iNaturalist should include at least one close-up photo, and, if possible a photo of the web. Any spider photo taken in Utah added to iNaturalist between 8/3-8/9 will be added to the event. How many spiders can you find? See the results here.
