Short General Description
A medium-sized black and yellow petaltail dragonfly.
Migration
false - false - false - Population genetics studies in Nevada (J. Simpkin, pers. comm.) indicate that odonates of dry regions such as the Great Basin may have very great dispersal potential, but whether this model fits for T. HAGENI because of the great distances between some of its EOs is impossible to determine at present. Dragonflies of the family Gomphidae, which may have similarly stringent requirements for larval habitat, have relatively poor dispersal abilities among dragonflies, so it is possible that T. HAGENI fits the gomphid dispersal model.
Non-migrant
false
Locally Migrant
false
Food Comments
Larvae eat terrestrial invertebrates such as spiders.
Ecology Comments
Needs water percolating through bog. Tall trees too near a bog might shade it most of the day, preventing ovipositing, or prolong its snowpack to late in season. Brush advances into the bog over time, eliminating habitat.
