If A. were a modern editor of his own text, he might perhaps have considered printing πλαγκτάς rather than the capitalisation which all editors (except Seaton 1912) have adopted. The two points at issue are as follows: first, Hera’s statement, ‘I saved them as they crossed through the W/wandering rocks’ is a reference to a speech in the Odyssey made by Circe to Odysseus - it can be no coincidence that Circe has just made an appearance in the Argonautica.
