South Vancouver Island has some Pacific
Forktails and they have been seen on Quadra Island opposite Campbell River. They
are not as common as the western forktails.
Pacific Forktail is a small little
damselfly. Only 2.5 cm in length, the male is nonetheless easily recognized by
the four tiny blue dots atop the black upper surface of the thorax.
Females have a bewildering array of
patterns as they change from immature to old, dark, pruinose adults. In all
cases, though, the abdomen is rather thin and long.
Beyond the thorax pattern, males are characterized by aqua blue sides to the
thorax, black atop the abdomen, and an extensive blue patch on several segments.
Note also the green lower half to the eyes and around the face.
Youngsters often have a thorax that is
white, tan, pale green, or pale blue, with thin side stripes, but apparently
some can even be orange.
All young female Pacific's, though, have orange spots between the eyes on the
back of the head.
