Aenictopecheidae
Aenictopecheidae is a rare family of true bugs (Hemiptera) with a worldwide distribution but limited species diversity. The family contains approximately a dozen described genera, with most species found in tropical and subtropical regions. The only North American representative, Boreostolus americanus, has been documented from mountain stream habitats in the western United States.
Heterocerus brunneus
Brown Mud-loving Beetle
Heterocerus brunneus is a species of mud-loving beetle in the family Heteroceridae. Adults and larvae construct burrow structures in substrates with variable moisture content, particularly in muddy or sandy sediments near water. The morphology of these burrows changes with substrate consistency, especially water content. The species has been studied for its paleoecological significance, as its burrows may be preserved as trace fossils. Field observations have been documented in northeastern Kansas.
