Insects always found in pleasant surroundings (4)
I believe the answer is:
ants
'insects' is the definition.
(ant is a kind of insect)
'in pleasant surroundings' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ANTS' is hidden within 'pleasant surroundings'.
'always found' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for ants that I've seen before include "Inhabitants of a formicary" , "Soldiers" , "Six-foot insects" , "Tiny insects that live in colonies" , "Small social insects" .)
