Predation of Telebasis vulnerata (Odonata: Coenagrionidae) eggs by detritivorous caddisfly larva, Phylloicus pulchrus (Trichoptera: Calamoceratidae)

After observing the presence of Phylloicus pulchrus (Trichoptera: Calamoceratidae) and tadpoles of Leptodactylus albilabris (Anura: Leptodactylidae) on submerged leaves with recently laid eggs of Telebasis vulnerata (Odonata: Coenagrionidae), we set up an experiment to determine if they were consuming Odonata eggs. We collected leaves from the stream, where consumers were positioned over egg masses, and…

Season and temperature dependent location of mating territories in Somatochlora flavomaculata in a heterogeneous environment (Odonata: Corduliidae)

In a heterogeneous environment, males of Somatochlora flavomaculata regularly occupy site-fixed locations away from water, adjacent to vertical landscape elements, and to a lesser extent, also at water, i.e. at oviposition sites. Territories both over land and over water are typically patrolled by continuous site-fixed flights. These places serve as rendezvous sites where copulation is…
