Zusammenfassung
Egg development and larval growth of Protonemura intricata (Ris, 1902) (Plecoptera: Nemouridae) were studied in the laboratory and in the Breitenbach, a small stream in Germany (F.R.G.). The length of embryonic development (Y, days) is strongly inversely temperature (T, °C) dependent. The length of dormancy is dependent on oviposition date, and is shorter the later that the eggs are laid. In the laboratory, P. intricata larvae from early batches with long dormancy grew faster than larvae from late batches with direct development. Final size was the same in both cases. This acted against the population synchrony induced through egg dormancy. Benthos samples suggest the same in the field.
