Life Cycles of Some Species of Plecoptera in Sierra Nevada (South of Spain),in the Sierra Nevada mountains (Southern Spain). Samples were collected using a net with a mesh size of 0.36 mm, and head width measurements were used as an indicator of nymphal size. Five species with as yet undescribed life cycles were investigated, viz.: . Aubert; . Klapalek; . Despax; . Aubert a

Ephemeroptera Emergence from a High Mountain Stream in Tyrol, Austria,, from June 1981 to October 1982. The emergence period was 2 to 2.5 months with only one peak. Most subimagines of both species emerge in August. Differences in the phenology of the emergence between the two sites resulted from differences in water temperature while differences between the two speci

Timing and Synchronicity of the Emergence of ,,g of a small Japanese stream in two seasons, from January to May 1982 and 1984. The developing zero (DZ) and the thermal constant (TC) of the last instar, estimated by a new method, were 8.8°C for males, 9.0°C for females and 151 °C day for males, 154°C day for females, respectively.

The rate of development (V) was given by the equation V = bT + a. Photoperiod length had no effect on the incubation period..Embryonic
