Right about now, these globs of “spit” are all over the place attached to plants in my garden and elsewhere. Ever wonder what they are?
Inside is actually a spittlebug nymph- sort of like a kid bug. The spittlebug protects itself by creating this spit mixed with air bubbles (also called spittle). The spittle keeps it safe from predators and also prevents it from drying out. Meanwhile, the bug inside eats away at the plant it is attached to.
Oh, and calling it “spit” is a bit misleading. It actually comes out of the bug’s rear end!
