Spiders

Maria Mitchell staff have been collecting spiders since 2006 and have accumulated more than 6,000 specimens representing about 250 species from Nantucket, Tuckernuck and Muskeget Islands (identifications are on-going). We try to answer several research questions: How many species live on the Islands? How does prescribed burning affect spiders? How do changes in Nantucket plant communities affect spider diversity?

In 2010, MMA scientists and volunteers began a new project to identify harvestmen (daddy-longlegs) on the island.  We found five species.
