10 of the 52 taxa in this habitat are Trichoptera
4.) List of Insects with Trophic Trait
-Baetis tricaudatus – Active swimmers, small hind wing, dive under water to lay eggs,
aquatic
-Camelobaetidius warreni - claws with relatively few denticles; and a labrum with
relatively few setae in the dorsal, submarginal anterior line and relatively many
sublateral setae, aquatic
-Fallceon quilleri – lives in same habitat year round (non-migratory), aquatic,
occurrences are roughly equivalent to populations
-Brechmorhoga mendax – active daytime fliers, The abdomen is narrow with an
expanded tip, mostly seen over streams
-Calineuria californica - largest western species of the Perlidae family, They are generally
a late spring/early summer emerger, they crawl out of the water to perch on streamside
riparian foliage or rocks where they shed their nymphal shucks, they also mate in the
same locations
-Ambrysus mormon – usually found at the bottoms of ponds/streams, true aquatic
beetle
-Corydalus texanus - wing lengths of up to 85 millimetres, sexually dimorphic, males
having large mandibles used to grasp the females during mating while the females have
smaller jaws
-Chimarra utahensis – complete metamorphosis, Mated females deposit eggs on the
surface of lakes, ponds, or streams, or dive below the surface to cement them on
submerged rocks or plants
-Hydropsyche californica – three life history stages, complete metamorphosis, welldeveloped legs on the thorax
-Microcylloepus pusillus – very small, herbivore, larvae and adults live in streams
(aquatic)
