About this book

Language: German

Caddisflies are insects whose larvae live in water and whose imaginal stage lives on land. They are a wanderer between two worlds and especially adapted to both aquatic life and airborne and life. The various mechanisms of adaptations make them interesting and the aim of this book is to give a better understanding of these insects.

To protect themselves, larvae build tubes from grit, plant parts and snail shells, or stretch nets which will catch food; others are predatory. All larvae and pupae, however, have in common that they breathe in water and need to overcome osmosis.

The adult animals have the ability to fly, often in large swarms, when the day changes to night. Swarms are nuptial flights in whichsupported by pheromones – pairs are formed, after which females soon lay eggs in the water or in its vicinity. After this the next cycle in their development starts..

The curiosity that provides this knowledge and enriches our science has a history that goes back a long way, at least to the Greeks and Romans. It is interesting to learn how over the centuries not only general knowledge grew, but also the knowledge of this particular insect order. Thus, the exposé on caddisflies in this book begins with a brief history of caddisfly research.


Summary in German:
Köcherfliegen gehören zu den Insekten, deren Larven im Wasser und deren Imagines an Land leben. Sie sind Wanderer zwischen zwei Welten und in besonderem Maße sowohl der aquatischen Lebensweise als auch dem Leben in der Atmosphäre angepasst. Die verschiedenen Mechanismen der Anpassungen machen neugierig. Sie näher kennenzulernen ist das Ziel dieses Buches.

Larven bauen zum Schutz Köcher aus Steinchen, Pflanzenteilen und Schneckengehäusen oder spannen Netze, in denen sich Nahrung verfängt; andere sind räuberisch. Gemeinsam sind allen Larven und Puppen die Atmung im Wasser und die notwendige Überwindung der Osmose.

Die adulten Tiere besitzen die Fähigkeit zu fliegen, oft in großen Schwärmen, wenn der Tag in die Nacht wechselt. Schwarmflüge sind Hochzeitsflüge, in denen sich – Pheromon gesteuert – die Paare finden, deren Weibchen schon bald im Gewässer oder in Gewässernähe Eiergelege absetzen. Der nächste Entwicklungszyklus beginnt.

Die Neugierde, die diese Kenntnisse schafft und unser Wissen bereichert, hat eine Geschichte, die weit zurückreicht, mindestens bis zu den Griechen und Römern. Es ist interessant zu erfahren, wie über die Jahrhunderte nicht nur das allgemeine Wissen, sondern auch die Kenntnis über diese Insektenordnung wächst. So beginnt die Darstellung der Köcherfliegen in diesem Buch mit einer kurzen Geschichte der Trichopterenforschung.
