Distribution map Cordulegaster heros

Map data based on J.-P. Boudot & V. J. Kalkman (eds.),
Atlas of the European Dragonflies and Damselflies


General ➤ a very large black-and-yellow species which occurs in Austria, North-East Italy, the Balkans and Greece
Classification • suborder: Anisoptera (dragonflies); family: Cordulegastridae
Scientific name Cordulegaster heros Theischinger, 1979
Distribution • click or tap the Map button above
Notes ➤ for an overview of the differences between the species in the boltonii and the bidentata groups, tap or click here
  • the female lays her eggs by thrusting her abdomen repeatedly into wet mud, moss, etc.
  • two species of the boltonii group very rarely co-occur at the same site; therefore if two Cordulegaster species co-occur, they very probably belong to different groups
  C. heros is noticeably bigger and darker than C. helladica with which it co-occurs (e.g. on the Peloponnese)
Habitat • small rivers and streams
Dimensions • typical body length: 77-96 mm; hindwing: 45-58 mm
Both sexesHead• the eyes are green (brown in immature animals)
  • the occipital triangle is black
 Thorax• the thorax is black with three yellow bands; the middle band is relatively well-developed
MaleAbdomen• each upper appendage bears one tooth on the underside (rather than two, as in the species of the bidentata group)
Photographs • all of our photos below were made on the Peloponnese in 2010 and 2015 and show the subspecies C. h. pelionensis

Line DrawingLineDrawing: the male's abdomen in dorsal view, and the male's head, thorax and abdomen in lateral view.

The boltonii group (left) and the bidentata group (right)
The former comprises C. boltonii, trinacriae, heros and picta.
The latter comprises C. bidentata, insignis and helladica.
In the boltonii group, note:
1. thorax: the middle band is (relatively) well developed,
2. upper appendages: close at base, then diverging, curved
(as opposed to separated at the base, then straight),
3. S1: the yellow spot sits at the bottom edge
(as opposed to the upper segment portion), and
4. anal triangle: typically five (as opposed to three) cells.
