Autumn Argiopes II

1 August 2020

Records of Argiope aurantia (Yellow Garden Spider) and Argiope trifasciata (Banded Garden Spider) for 2020 started getting posted a couple of weeks ago. These two species are some of the most photographed spiders in Minnesota thanks to the female spider's habit of sitting in her web in sunny locations like prairies and gardens. These species are easy to distinguish from one another and no other orb weavers match either their size or bold patterns.

Last fall the members of this project joined forces to find 13 new county records for Argiope aurantia and 12 new county records for Argiope trifasciata. But we still haven't recorded these species in every county in Minnesota so I'm throwing down the gauntlet once again! Can we make these two species the first two spiders known from every one of Minnesota's 87 counties?

The following 35 26 counties have no records of Argiope aurantia:
Aitkin, Beltrami, Big Stone, Carlton, Cass, Clearwater, Cook, Crow Wing, Grant, Houston, Hubbard, Itasca, Kanabec, Kittson, Koochiching, Lake, Lake of the Woods, Mahnomen, Marshall, Meeker, Mower, Murray, Nobles, Otter Tail, Pennington, Pine, Polk, Pope, Red Lake, Redwood, Roseau, St. Louis, Swift, Traverse, Wadena

The following 34 29 counties have no records of Argiope trifasciata:
Aitkin, Benton, Big Stone, Cass, Clearwater, Cook, Dodge, Fillmore, Freeborn, Goodhue, Hubbard, Itasca, Kanabec, Kandiyohi, Koochiching, Lake of the Woods, Mahnomen, Marshall, Martin, McLeod, Mille Lacs, Morrison, Murray, Norman, Pennington, Pope, Red Lake, Roseau, Sibley, Steele, Swift, Todd, Wadena, Wilkin

I'll update this post as new county records get established. Happy spidering! (yeah, that's a thing!)
