Beetles wandering round in cooler peat (10)

I believe the answer is:

coleoptera

'beetles' is the definition.
(I've seen this before)

'wandering round in cooler peat' is the wordplay.
'wandering round in' indicates an anagram.
'cooler'+'peat'='coolerpeat'
'coolerpeat' with letters rearranged gives 'COLEOPTERA'.

(Another definition for coleoptera that I've seen is " beetles".)

I've seen this clue in The Guardian.
