Most larvae of marsh beetles are quite at home in the water; many can swim and dive with alacrity. Some live on branches that are partially submerged; others live among the leaves on the bottom of ponds; others are found in the water in tree-holes; still others make their homes in wet moss.
Adults are usually found on foliage near water; many species are attracted to lights. Adults of some species may be found on flowers.
Adults of the genera Scirtes andOra have thickened hind femora and sometimes jump like flea beetles. Elodes species gyrate like Whirligig Beetles when they fall into water (White, 1983).
