Dragonflies are masters of using the ipsilateral wing-wing interaction for different kinds of flying modes. It has been discovered that the phase difference between ipsilateral forewings and hindwings plays important role on wing aerodynamic performance. In the current study, we continue our research of a modeled dragonfly in slow flight (Liang and Dong (2009)) by varying the phase difference b...

The predatory labial strike of dragonfly (Aeschna) larvae could be elicited by an artificial water jet stimulus. The larvae showed fair prey-catching ability even when visually deprived, whereas when deprived of mechanosensory and visual information, the ability decreased sharply. Also, immobilized prey were unable to elicit a strike even from intact larvae. The percentage of labial strike (PLS...

Abstract The female of the biting midge Forcipomyia paludis is a dipteran ectoparasite West Palaearctic damselflies and dragonflies, sucking haemolymph mainly from wing veins their hosts. This tiny remains firmly attached to wings even during fast flight aerial fight maneuvers as shown in present paper by field studies large dragonfly, Cordulegaster boltonii . Since individuals F. attach themse...
