The toad bug, Gelastocoris oculatus (Fabricius) (7-9 mm) are cryptically mottled and vary from brown and black to reddish-yellow. They are found on muddy or sandy shores of ponds, lakes, streams, and rivers. These predatory insects have mantid-like raptorial forelegs used for capturing small insect prey. Both adults and nymphs are active from spring through fall; there is one generation produced annually. This species is widespread in Virginia and is found in southern Ontario and throughout the United States and into Mexico.
