The rhubarb plants went to seed a few weeks ago, & when they do, a big stalk shows up in the middle of the rhubarb bush, & it has a huge cluster of tiny round seeds on it. It dried up a while ago when the rhubarb stopped growing, & the stalk became brittle & hollow. A few days ago I cracked it open,  & earwigs started just pouring out of the stalk. It was completely stuffed with them! A lot of people hate earwigs, because they can destroy gardens, & earwigs do eat some plants, but they are also a big predator of mites & aphids, which are probably worse for your garden than earwigs are.
