Glyptotendipes paripes
Glyptotendipes paripes is a non-biting midge (Chironomidae) with a univoltine life cycle in temperate regions. Larvae are filter-feeders that inhabit lake and pond sediments, consuming planktonic diatoms and sestonic particles. The species is known from both European and North American populations, with well-studied populations in central Florida lakes and prairie ponds. Larval distribution is strongly influenced by sediment organic content and particle size, with highest densities in fine, organic-rich sediments.
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.
