| Abstract: | Aspects of the phenology, reproductive biology and larval cycle of natural populations of the Calopteryx haemorrhoidalis (Vander Linden, 1825) are described. Populations of this species in Brabtia sector (eastern Numidia, North-East Algeria) were studied between March 2017 and April 2018. An overview of the current state of the population is provided. The streams of Eastern Numidia have suffered over recent years from major disturbances including the effects of 20 rapid climate changes. Although the status of autochthony is preserved in the site, the populations are currently diminished compared to that recorded two decades ago. Aspects of the species reproductive behavior, biology, and ecology are reported. The species is univoltine with a direct development in 12 larval stages. The effects of some climatic conditions, particularly air temperature, included an extension of the adult phenology period. The species is unable to tolerate a certain amount of stress similar to stagnant water species. The correlation established between the abundance of C. haemorrhoidalis and the physico-chemical parameters from the principal correspondence analysis (PCA) shows an ecological gradient, in the distribution of the species, significantly (P<0.001) explained by a requirement for dissolved oxygen, both temperatures and pH. |
