They have therefore changed their flapping modes.- \u003cstrong\u003eCatching prey.-\u003c\/strong\u003e Unique catching of flying insects in the air with specially equipped catching legs.- \u003cstrong\u003eFighting\u003c\/strong\u003e Never before seen images document collisions, rollovers and injuries. The legs with claws and bristles as well as the mouthparts have proven to be the main weapons.- \u003cstrong\u003eDefense of males\u003c\/strong\u003e Females mitigate sexual conflicts with sophisticated defenses. At high densities, males always and everywhere try to catch females and bring them to mate, females fly better and often fight successfully.- \u003cstrong\u003eInterspecific discord\u003c\/strong\u003e in competition for territories or perches also occurs between species. An unusual behavior was documented: a male damselfly carries a tandem of feather dragonflies away with its legs.- \u003cstrong\u003eColors \u003c\/strong\u003eDragonflies often look very colorful. These colors are caused by light refractions on structures or by color pigments.- \u003cstrong\u003eThreatening\u003c\/strong\u003e is carried out by presenting wings or by a large number of threatening flights. It is energetically more favorable than fighting and reduces the risk of injury. Males display courtship with colored wings. In the case of damselflies, the flapping frequency is doubledand a species-typical phase relationship of the fore and hind wings is used. This provides females with information for their choice of mate (female choice).- \u003cstrong\u003eMating\u003c\/strong\u003e of damselflies gave famous data on genegoism, as the males almost completely remove the seed of a predecessor from the female and replace it with their own.- \u003cstrong\u003eOviposition\u003c\/strong\u003e is a dangerous activity for damselflies and some damselflies that bore their eggs into plants. More modern groups drop the eggs from flight. Some females dive under water to lay their eggs. At high densities, alternative methods are used to avoid the males.- \u003cstrong\u003eLarvae\u003c\/strong\u003e are ambush hunters under water with a range extension of the unique capture mask, which can reach very high speeds.- \u003cstrong\u003eHunting\u003c\/strong\u003e More than half of them are eaten by frogs and birds when they hatch and lay their eggs. Egg-laying dragonflies flee sideways in order to get as quickly and far away from the frogsas possible. Hatching often takes place at night and in groups. This reduces the risk of being eaten.- \u003cstrong\u003eHatching\u003c\/strong\u003e metamorphosis with risk of accident, as the moist body tissues of the larval skin and the flying insect have to separate before drying sets in. Hatching accidents are not uncommon.- \u003cstrong\u003eMaiden flight\u003c\/strong\u003e is an important moment in which the innate flight pattern must function immediately.- \u003cstrong\u003eEcological significance.- Response to climate change.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Default Title","offer_id":53198331904343,"sku":"9783662702338","price":999.99,"currency_code":"GBP","in_stock":false}],"url":"https:\/\/bookcurl.com\/products\/dragonfly-behavior-9783662702338","provider":"Book Curl","version":"1.0","type":"link"}
