NEUROPTERA, Sialidae -- <Images> & <Juveniles> Please refer also
to the following links for details on this group: Sialidae = Link 1 The alderflies are a small family and the larvae of Sialis and several other genera are
entirely aquatic feeding partly on other aquatic insects and smaller animals
in their environment. Adults are
dark, ca. 25 mm. max. long. The eggs are
laid in masses on vegetation over or near water. The larvae differ from the Corydalidae by having a terminal
filament, seven pairs of lateral filaments and no hooked anal prolegs. Sialids have not been used in
biological pest control, but are certainly important in the natural control
of insects in aquatic habitats.
