Orton (1914) observed that ten month old individuals of Serpula vermicularis in the south west of England could successfully reproduce.
Larval settling time
The length of the planktonic stage is unknown but comparison with other serpulid species suggests it may be between six days and two months (Holt et al., 1998).
Spawning season
Spawning seems to occur in the summer. In the Clyde area Elmhirst (1922) observed spawning to occur in June to August and in Plymouth ripe individuals were seen in August and September (Allen, 1915).
