First record of Ceriagrion fallax Ris (Odonata: Coenagrionidae) preying on small web-building spiders (Arachnida: Tetragnathidae)

In montane forest of south-western Yunnan, China, a female of Ceriagrion fallax was observed and photographed preying on a small web-building spider of the genus Leucauge. This is the first record of plucking an orb-weaver spider by a representative of the genus Ceriagrion. A brief discussion on the evolution of spider feeding behaviour in odonates…

First record of Telebasis filiola Perty (Odonata: Coenagrionidae) preying on small web-building spiders (Arachnida: Tetragnathidae)

At a wetland in southeastern Mexico a female of Telebasis filiola was observed and photographed preying on a small web-building spider of the genus Leucauge. This is the first record of gleaning by a representative of the genus Telebasis. A brief discussion on this subject in other odonates is provided.

Factors influencing predation on Odonata by Argiope trifasciata (Forsskål, 1775)

Despite a high number of incidental online records of spiders predating upon dragonflies/damselflies, studies on these interactions are scarce. Here, we describe the predatory behavior of Argiope trifasciata on the two most common odonate species in the study area.

Ecology of Mesamphiagrion laterale (Odonata: Coenagrionidae): abundance, reproduction and interactions with co-occurring species

The behavior of Mesamphiagrion laterale (Selys, 1876) is described based upon 2430 hours of observation. A total of 2820 individuals were observed for 270 days from 2014 to 2015 using mark-recapture. Probabilities of resight, highest reproductive activity, time-perch and time of perch-temperature were statistically analyzed. Mesamphiagrion laterale is not a territorial species, the individuals perch…

Wing surface in the damselfly Mecistogaster ornata (Zygoptera, Pseudostigmatidae): interactions between nanoscale wax and sticky spider webs

The representatives of the damselfly family Pseudostigmatidae are known for their ability to catch small orb web spiders, or in some cases small kleptoparasitic spiders in the webs of other spiders. In this paper, I demonstrate that the nanoscopic crystalline wax coverage of wings in the pseudostigmatid damselfly Mecistogaster ornata is partially altered due to…

To stay or not to stay: Decision-making during territorial behaviour of Calopteryx haemorrhoidalis and Calopteryx splendens splendens (Zygoptera: Calopterygidae)

The effect of copulation and presence of predators on territorial behaviour of male Calopteryx haemorrhoidalis (in southern France) and of male C. splendens splendens (in northern Germany) was studied in nature. A male obtaining a copulation early in the day often secured more copulations later that day than did males not obtaining an early copulation….
