Distribution of gerrid larvae over zones of microhabitat grain was studied in the laboratory. Gerris argentatus obeyed the pattern in nature when all the instars were present (density of youngest instars peaked in the fine-grained zone, of imagoes in the open-water space, and of the two oldest larval instars in the middle zone), but the numbers of all instars of G. lacustris peaked in the middle zone. In experiments with 1st instars, 3 Gerris species preferred the open-water zone, but… CONTINUE READING
