Spotting

The type of Argiope may be important. I have images of Argiope keyselingi egg sacks and they are green pouches.

No, I did not see an Argiope. Then again I'm not in that part of my garden much. I was pulling weeds around some plants tucked in the back if the border.

I found something similar in my garden this late summer. There were two round masses like your two, tied to a milkweed plant. I learned that they were Argiope spider egg cases. I did have an Argiope living in the same flower bed for most of the summer. Do you remember seeing an Argiope near by?

Not enough evidence either way. It could still be eggs and someone who knows better will eventually come along and make the ID. I would leave it as it is I think

Hmm...do you think I should remove it from this mission? I assumed eggs.

either that or wrapped spider detritus from bugs a spider ate
