Abstract

Egg masses and eggs of Sialis hasta, S. iola, S. joppa, S. infumata, S. aequalis, S. vagans, S. glabella, S. mohri, S. velata, and S. itasca are described using SEM micrographs. Diagnostic characteristics of chorion surface and micropylar structure and a key for specific determination of eggs of these 10 species are given. Oviposition is confined to leaves and twigs near or overhanging water. Eggs are oriented either vertically or horizontally in the egg mass, and hatch in 5 to 10 days in the laboratory. Hatching larvae are aided by an egg burster which tears the chorion and aids in removing the embryonic envelope.

Résumé

Les masses d’oeufs et les oeufs de Sialis hasta, S. iola, S. joppa, S. infumata, S. aequalis, S. vagans, S. glabella, S. mohri, S. velata, et S. itasca sont décrits à l’aide de micrographies en MEB. Des caractères diagnostiques de la surface du chorion et de la structure du micropyle sont fournis, de même qu’une clé d’identification des oeufs à l’espèce pour les 10 espèces ci-dessus. Les oeufs sont déposés sur du feuillage ou des branchettes près de, ou surplombant, l’eau. Les oeufs sont orientés verticalement ou horizontalement dans la masse d’oeufs et, au laboratoire, ils éclosent en 5 à 10 jours. Lors de l’éclosion, la larve s’aide d’un ovorupteur qui déchire le chorion et facilite le rejet de l’enveloppe embryonnaire.
