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.

Hi Lynette,

How did you then get to grandiosa for this juvenile male?

Sorry, snow blindness!

BTW, I saw your expedition in Rod's collecting journal. Looked like a lot of fun.
