Patterns of variation in wing venation of Iberian Cordulegaster boltonii (Donovan, 1807) (Odonata: Cordulegastridae)

International Journal of Odonatology, 2023
Some structural characters, such as wing venation, have been used in odonates to differentiate taxa. In Cordulegaster boltonii, a species widely distributed throughout the western Palaearctic, the main characteristics of its wing venation have not been quantified until now.

The life cycle of Cordulegaster boltonii (Donovan, 1807) (Odonata: Cordulegastridae) in the Sierra Morena Mountains (southern Spain)

Hydrobiologia, 1999
The life cycle of the dragonfly Cordulegaster boltonii was studied for five consecutive years, mainly by systematic sampling of larvae, in a permanent upland stream in southern Spain, towards the southern part of this species' range. The instar distribution during winter is that of a ‘spring species’ (Corbet, 1964) in which larvae destined to emerge in

Reprodukční chování samců páskovce kroužkovaného (Cordulegaster boltonii)

2017
Communication among animals often relies on visible signals and the ability to compatibly perceive them. Correct signal perception is especially important for animals with male sexual selection. In my master's thesis, I am addressing the issue of how does a male golden-ringed dragonfly (Cordulegaster boltonii) recognize a female of the same kind and ...

Vliv individuálních vlastností samců páskovce kroužkovaného (Cordulegaster boltonii) na jejich epigamní chování

2018
My study researches the individual male characteristics of Cordulegaster boltonii in relation to their epigamic behavior. The first part of this study analyzes the relations of the measured characteristics (length and height of the wing, wings area, body weight, age), in the second part I assess their possible effect on the epigamic behavior of males ...
