English:

Kingdom: Animalia; Phylum: Arthropoda; Class: Insecta; Order: Megaloptera; Family: Sialidae

Alderflies are megalopteran insects of the family Sialidae. They are closely related to the dobsonflies and fishflies as well as to the prehistoric Euchauliodidae. All living alderflies - about 66 species altogether - are part of the subfamily Sialinae, which contains between one and seven extant genera according to different scientists' views. But in most classifications, all or almost all of these are treated as subgenera of Sialis. Sialinae have a body length of less than 25 mm, long filamentous antennae and four large dark wings of which the anterior pair is slightly longer than the posterior. They lack ocelli and their fourth tarsal segment is dilated and deeply bilobed. Dead alderfly larvae are used as bait in fishing. The females lay a vast number of eggs upon grass stems near water. The larvae are aquatic, active, armed with strong sharp mandibles, and breathe by means of seven pairs of abdominal branchial filaments. When full sized, which takes between one and two years, they leave the water and spend a quiescent pupal stage on the land before metamorphosis into the sexually mature insect. Adult alderflies stay near to the water, in which they had lived in when they were younger.

Deutsch:

Klasse: Insekten; Überordnung: Neuflügler; ohne Rang: Netzflüglerartige; Ordnung: Großflügler; Familie: Schlammfliegen

Merkmale:
Die Tiere haben einen relativ kleinen und plumpen Körperbau mit Vorderflügellängen von 10 bis 20 Millimetern, dabei sind die Weibchen in der Regel größer als die Männchen. Sie sind überwiegend braun gefärbt und haben keine Punktaugen (Ocelli). Ihr Halsschild ist relativ breit und auch weniger lang als es breit ist. Ihre Beine sind kräftig gebaut und haben fünf Tarsenglieder. Das vierte Glied ist lappig verbreitert. Wie auch die anderen Großflügler haben sie eine stark hervortretende Flügeladerung auf ihren großen Flügeln, die in der Ruhestellung dachartig über den Körper gelegt werden. Die Larven haben am Hinterleib sieben Paar charakteristische, gefiederte Kiemen und ein langes, spitz zulaufendes Hinterleibesende. Sie haben große Mandibeln.
Lebensweise:
Die Imagines sind tagaktiv und fliegen nur träge. Man findet sie in Mitteleuropa von Mai bis Juni auf der Ufervegetation, sie leben aber nur kurz. Die Weibchen legen bis zu 2000 Eier in Gruppen von etwa 200 Stück an der Ufervegetation verschiedener Gewässertypen ab. Die daraus schlüpfenden Larven lassen sich ins Wasser fallen. Sie leben anfangs im Wasser, später im Schlamm vergraben. Sie kommen bis in 18 Meter Tiefe vor. Sie ernähren sich räuberisch von Insektenlarven, Würmern und kleinen Muscheln. Sie benötigen meist zwei Jahre für ihre Entwicklung, überwintern beide Male als Larve und durchleben 10 Larvenstadien. Sie verpuppen sich am Ufer unter der Erde. Die Puppe gräbt sich vor dem Schlüpfen der Imago an die Oberfläche.
