Insects

All planted vegetation at the enhanced sites had greater taxa richness, overall densities and hemipteran insect densities (mostly aphids) than the adjacent armored shorelines.  Thus, production of certain insects associated with vegetation has increased, while others such as dipterans (flies, e.g., chironomid midges) have not increased since enhancement.  Diptera and Hemiptera are both juvenile salmon prey items, and were common in neuston tows on the water’s surface at the sites.
