New data on the distribution of Large Golden Ringed Dragonfly (Cordulegaster heros Theischinger, 1979) (Odonata) in Zselic hills [PDF]

Natura Somogyiensis, 2009
The earliest record of this species is dated back to 2005. Intensive investigations, habitat mapping and ecological research of C. heros were started in 2008. Our researches were focused on the larval instars and also on the conservation of the habitats. Most of the discussed C. heros populations were strong with high abundance.

Life history and multiscale habitat preferences of the red-listed Balkan Goldenring, Cordulegaster heros Theischinger, 1979 (Insecta, Odonata), in South-Hungarian headwaters: does the species have mesohabitat-mediated microdistribution?

Hydrobiologia, 2015
Life cycle and microdistribution patterns of Cordulegaster heros, a charismatic species for nature conservation, are poorly known. Life history characteristics and multiscale habitat preferences of the larvae were followed for one year in monthly intervals by systematic samplings in eight headwaters, which resulted in data on 2562 individuals.

Emergence behaviour of the red listed Balkan Goldenring (Cordulegaster heros Theischinger, 1979) in Hungarian upstreams: vegetation structure affects the last steps of the larvae

Journal of Insect Conservation, 2015
In odonates, the emergence behaviour and finding suitable substrates for successful molting may influence the next generation and ultimately can determine the survival of the entire population. Understanding emergence behavior of endangered species and those granted special conservation status is particularly important.

Larval habitats and longitudinal distribution patterns of Cordulegaster heros theischinger and C. bidentata seŽlys in an Austrian forest stream (Anisoptera: Cordulegastridae)

Odonatologica, 2001
From May 1997 to April 1998 larvae were recorded at the Weidlingbach, a fourth order tributary of the Danube nr Vienna, at 12 sampling stations from source to mouth. From the 14 larval instars reported for the genus, 5 (F to F-4; based on head width) could be identified in both spp.; head widths of larvae were significantly larger than in.
