Ecology: |
|
Reproduction: |
This
species is very closely associated with spring-fed streams,
and generally remains close to where it emerged. It probably
has the longest flight season of any dragonfly or damselfly
in our area. |
|
The
males set up territories at choice breeding sites. After
males and females mate, the male remains attached to the
female (called "in tandem") as she oviposits in vegetation
at spring-fed streams. |
