Jansy,
Krolik is Russian for "rabbit"
Larva = lavra ("big monastery")
Larvy (larvae) = lavry ("laurels")
The lavry/larvy wordplay occurs in "Drugie berega"
(Russian title of Speak, Memory), Chapter Six.
Besides, in Slavic myths, lyarva (it also
comes from larva, Latin for "mask") is female evil spirit. The
woman, whose body it chooses to live in, becomes a whore. Lyarva is
also one of several vulgar words meaning "whore."
best,
Alexey
