Spider - Aculepeira - Female
Naches Trail Preserve, Pierce County, Washington, USA
April 22, 2010
Size: around 10 mm
Found in the same bush as


Rod's comments were dead on, the retreat of the female was a platform and the retreat of the male was a dome. Finding the two in the same little bush had me quite confused last night. I though I was going to have to revise my entire concept of Aculepeira.

Moved
Moved from Spiders.

From Rod Crawford:
The female is clearly an Aculepeira. The male (which is juvenile)
looks more like a Metepeira.

The web retreats should tell the story. Metepeira make a little tiny
dome (something like the web of Neriene radiata but much smaller) to
hide under when they are not in their web. Retreat of Aculepeira is
more like a tube or platform.

The Aculepeira you would find in that environment is an undescribed
species of the A. packardi group. The Metepeira would likely be M.
grandiosa, but M. foxi is possible. We got both adult and juvenile
Aculepeira, and juvenile Metepeira, at our prairie site NW of
Rochester last week.

Pretty!
I'm thinking it is a Metepeira. Will be interested to see your own opinion.
