Large beast and two insects circling husband (8)
I believe the answer is:
behemoth
'large beast' is the definition.
'behemoth' can be an answer for 'beast' (I've seen this before). I'm not certain of the 'large' bit.
'two insects circling husband' is the wordplay.
'two insects' can mean two substitutions for 'insect'.
'insect' becomes 'bee' (bee is a type of insect).
'insect' becomes 'moth' (moth is a kind of insect).
'circling' indicates putting letters inside (circling can mean going around or containing).
'husband' becomes 'h'.
'bee'+'moth'='beemoth'
'beemoth' placed around 'h' is 'BEHEMOTH'.
'and' is the link.
Can you help me to learn more?
(Other definitions for behemoth that I've seen before include "Something huge and monstrous" , "big beastly type" , "Gigantic beast in Job" , "Abnormally large creature" , "Something of impressive size or power" .)
