The food habits and prey base of the endangered,Southwestern Willow Flycatcher (Empidonax traillii extimus) are Dragonflies and damselflies were recorded in just slightly lower numbers than. Researchers also look to dragonflies as ecological indicators. The presence of dragonflies indicates fresh water. One of the most useful dragonfly facts is that they reside low in the food chain, so scientific study of their numbers and their health can reveal changes in water ecosystems more quickly than studying other animals or plants.
