Pressure from palaver about silkworms, perhaps (6)
I believe the answer is:
larvae
'silkworms perhaps' is the definition.
(silkworm is a kind of larva)
'pressure from palaver about' is the wordplay.
'pressure' becomes 'p' (abbreviation).
'from' is a deletion indicator.
'about' indicates an anagram.
'palaver' with 'p' taken away is 'alaver'.
'alaver' is an anagram of 'LARVAE'.
(Other definitions for larvae that I've seen before include "Insects in immature state" , "Immature forms of invertebrates" , "Insects in the first stage of life" , "Insects just out of the eggs" , "Immature forms of insects" .)
