I grabbed the section of vine, broke it off, and put it in a mason jar.
I finally took to social media to find the answer, posting in a group that gardens. Lucky me, it turns out it was a cocoon made by a praying mantis! People pay to get mantis eggs (cocoons) because of how beneficial they are for gardens, and here I just stumbled across one!
One egg sack can contain up to 200 babies. Being carnivorous, these are a blessing for natural pest control in the garden! (Read more about mantis benefits and facts here.)
I now have this egg sack, in the above jar, in my refrigerator. I plan on waiting until planting season (when we have plants already coming up for cover/protection) to bring it out to hatch.
Here's hoping we have a couple survive and stick around this summer!
