Also called “pond skaters” and “water spiders,” water striders are hard not to notice. Water-repellant hairs on the hind and middle legs allow these nimble insects to skate on the surface of the water.
Groups of these aquatic beetles swim on the surface of water in quick, random patterns, searching for food. They have two pairs of eyes—one pair above the water, and one pair below—which helps them to quickly and accurately capture their prey.

This crayfish occurs only in Missouri, especially in the Black River and its tributaries. It is a stout, reddish-tan to dark brown species with numerous blackish specks and blotches on the pincers, carapace and abdomen.
