This large family is represented in North
America by two species that some consider co-specific. These are
one of our smallest damselflies. They
are distinctive in the field
with their black and red coloration, unmarked thorax, small size, and
relatively short, thick abdomen. The eyes are a rusty brown to red
and lacks postocular spots.
The Eastern (Amphiagrion
saucium) and the Western (Amphiagrion abbreviatum) are similar in
appearance but may be differentiated by size and examination of the male
terminal appendages. |
