Neoscona oaxacensis-ventral - Neoscona oaxacensis - Female
Salt Lake City, Salt Lake County, Utah, USA
July 31, 2004
Size: 35-45mm
Large spiders found around the Great Salt Lake. The huge number of spiders gets local media attention every year. Would like to narrow the ID down as much as possible.

other set
Kerry, what do you think about ? The posting has the same description as yours. Are they all the same species?

 
GSL spiders
Probably the same species, variation in pattern could be age related. I have three Neoscona species on my Utah list, unfortunately not the diagnostic characteristics or ranges. If time permits, I may be able to sample the perimeter of the lake and get a better idea of what the population(s) might consist of. The biomass of these spiders around the lake might easily be measured in tons when at it's peak.

Do you have a photo of the other side of the spider?

 
Have the ID
Just got an ID that should be good. Thanks to Dr. Cushing of the Denver Museum. A dorsal will be included with the set.
