At a summer-dry stream on the Aegean island of Lesvos, a population of Chalcolestes parvidens (Artobolevski, 1929) was studied during the reproductive period from late August to November 2018. Mediterranean intermittent streams display unique characteristics with a seasonal sequence of abiotic and biotic regulation and provide valuable habitats for C. parvidens. Abundance at the breeding water and perching positions on plants of males, females and pairs were recorded, and a mark-recapture study with 412 males was conducted. The damselflies perched mostly on dry plant parts of Salix fragilis and Nerium oleander that dominated the site. Males perched mainly on exposed twig tips near or over the water and some individuals were quite philopatric. A minimum adult male life span of 30 days after maturation was determined. Oviposition was observed exclusively in branches of S. fragilis. Differences in reproductive behaviour between C. parvidens and its sister species C. viridis appear to be very small or not distinguishable at all.
