Insect entangled with a net (5,3)
I believe the answer is:
white ant
'insect' is the definition.
(white ant is a kind of insect)
'entangled with a net' is the wordplay.
'entangled' is an anagram indicator.
'with'+'a'+'net'='withanet'
'withanet' with letters rearranged gives 'WHITE-ANT'.
(Other definitions for white ant that I've seen before include "Termite" , "insect" , "Social worker" .)
