- The Migrant Hawker
is a south eastern species with a late flight period. It
has has expanded its range in Britain recently, having
originally established itself as a breeding species in
the 1940s. It is very similar to the Common
Hawker - see Dragonflies and Damselflies 17 but the antehumeral stripes of
the Migrant Hawker are much reduced and the small yellow
triangle on the second abdominal segment is absent in the
latter species. Despite its name the Common Hawker is
actually quite an uncommon insect in the south east of
England. Migrant Hawkers are generally less territorial
than most of the other large hawkers and they may
therefore be seen in quite high densities, patrolling
woodland clearings in small groups. They are also far
easier subjects for photography than most of the other Aeshna
species. Another illustration of a male is shown on Dragonflies
and Damselflies 1
- The Black Darter
is the smallest of the Sympetrum
species found in Britain. It is widely distributed with
the strongest colonies in the north and west. The black
colour of the fully mature male (see Dragonflies and Damselflies 28) is normally
diagnostic in areas not also inhabited by the White-faced
Dragonfly and there is little overlap of flight
period between these two species. However, the females
and immature males are predominantly yellow so there
could be confusion with other darters during the early
part of the flight period (July - September). See Dragonflies
and Damselflies 1 for a head-on view of this species. The
ventral 'spine' of the female is clearly visible in the
photoghraph.
- See Dragonflies
and Damselflies 2 for an additional
illustration and information about the Southern
Hawker. The predominantly green markings are
clearly shown.
- See Dragonflies
and Damselflies 1 and 5 for additional illustrations and
further information about the Scarce Chaser.
The extended black markings on the wings of the female
are evident in the photograph.
