✦ Synopsis

The distribution of eggs and early larval stages of the myctophid fish Benthosema pterotum was studied during three cruises to the Gulf of Oman during January to February 1981 and February 1983. The eggs and yolk sac larvae were identified and described after artificial fertilization on board the Research Vessel "Dr. Fridtjof Nansen". The mature fish spawn in the Gulf at 300 to 100 m depths during early night. The eggs and smallest larvae were found at 300 to 200 m depths. The eggs hatch within 12 h at 21 ~ Hatching occurs before the slightly buoyant eggs reach the upper 50 m of the water column.

The oviposition behaviour of the water-lily beetle Galerucella nymphaeae was examined. This species is a specialist herbivore on the floating leaves of nymphaeids Nymphaeaceae and especially on the yellow water-lily, Nuphar lutea. Females lay their eggs in clutches on the leaves, and after hatching,
