Note
A 3-year study was conducted on a population of Nicolea zostericola (Oersted: Grube, 1860) at Nahant, Massachusetts (USA), which indicated that this species has a life span of about 1 year. Spawning occurred from mid-April to early July, after a rise in sea-water temperature. Pair formation occurred between sexually mature adults prior to and during spawning. Eggs were deposited in cocoons, where development occurred in 14 to 22 days. Larval development is described along with juvenile and adult substrate preferences and behavior.
