Egg sac identification
I have an egg sac I need help identifying. They're on the branches of Magnolia 'Ann', a deciduous magnolia. The eggs are pinkish and held together by a cottony white material, and the whole thing is covered by a shiny brown scale-like shell, and that is covered by more cottony material. There ads thousands of eggs in each sac. When crushed it exudes a thick yellowish goo, but it's completely separate from the egg sac and seemingly attached to the shell. I've been searching thru spider eggs and scale eggs and other insect eggs but haven't found anything close yet.
