Here's Mama & her egg sac.

The sac is about an inch across. The web threads holding it are different from the regular web thread. They are stiffer. They hold the sac suspended between the leaves. When the wind blows, these threads keep the sac from being blown against the plant it's attached to, and possibly being damaged. (Isn't nature amazing?)

I usually over-winter the canna (in its pot) in my mother's basement. However, because of the egg sac, I decided to sacrifice the canna & see what happens.
