"What Do We Have Here"
Female spiders produce either one egg sac containing several to a thousand eggs or several egg sacs each with successively fewer eggs. Females of many species die after producing the last egg sac. Others provide care for the young for some period of time; these females live one or, at most, two years. Females of the mygalomorph spiders may live up to 25 years and those of the primitive haplogyne spiders up to 10 years.
The protective egg sac surrounding the eggs of most spiders is made of silk. Although a few spiders tie their eggs together with several strands of silk, most construct elaborate sacs of numerous layers of thick silk. Eggs, which often have the appearance of a drop of fluid, are deposited on a silk pad and then wrapped and covered so that the finished egg sac is spherical or disk-shaped. The females of many species place the egg sac on a stalk, attach it to a stone, or cover it with smooth silk before abandoning it. Other females guard their egg sacs or carry them either in their jaws or attached to the spinnerets.
I found this Four-spotted Pennant Dragonfly checking out what I think is a Spiders Egg Sack at Joe Overstreet Landing in Osceola County, Florida.
