Identification
Gelastocoris rotundatus can be distinguished from the sympatric G. oculatus by its more restricted southwestern distribution in North America. The two share the characteristic of enlarged, forelegs adapted for seizing prey.

Habitat
Associated with margins of water bodies, including intermittent creeks and streams. The occupies riparian zones where it can blend with substrates such as rocks and soil.
Distribution
Southwestern United States (restricted to this region in North America) and Central America. GBIF records indicate presence in Middle America and North America.
Diet
Predatory. Like other Gelastocoridae, feeds on small prey captured with forelegs.
Behavior
Exhibits cryptic coloration that provides effective camouflage against rocky and soil substrates. When disturbed, may remain motionless or move short distances rather than taking .
Ecological Role
in riparian and shoreline , contributing to regulation of small in aquatic margin .
Human Relevance
Occasional subject of macrophotography due to its cryptic appearance and unusual body form. No known economic significance.
