Another Wetland Walk
Mill Creek Metroparks outside Youngstown are restoring an old fish hatchery into a wetland wildlife preserve. While parts still contain a lot of exotic invasives, there were quite a lot of nice insects and plants to observe. This is the same place I found the Bald Eagles nesting last spring.
Near the edge of the ponds were these floating plants known as Bladderworts. I once found five different species at one location. Some float, others are submerged. Some have no leaves, others have single, double, or triple branched leaves under the water. They all contain bladders, or little balloons that inflate when their triggers are touched. They suck in small invertebrates from which they gain additional nutrients. In other words, they are carnivorous plants. I believe this one is the Common or Greater Bladderwort, Utricularia vulgaris.
