Damselfly Abdominal Patterns

The amount of color on the abdomen can be an important clue to ID.  Also pay attention to the pattern and shape of the coloring. Especially note the coloring of the terminal segments 8, 9 & 10; the extent of coloring at the tip may be more important than the overall color of the rest of the abdomen.

Note the large amount of black on the abdomen of this Taiga Bluet

Here the abdomen is largely blue with variable black distal rings on each segment

In this case, the black forms sharply pointed arrows into the blue.

In identifying Bluets, the blue species can be grouped into two categories, the ones with mostly blue abdomens and those with  black abdomens.  The exact amount of blue is extremely variable within each species, both individually and geographically, so attempts to narrow them more than this usually fail.

When identifying Spreadwings, the presence and pattern of pruinosity on segments 8-10 are significant.
