Part of flytrap hid some bugs (6)
I believe the answer is:
aphids
'bugs' is the definition.
(a type of bug)
'part of flytrap hid some' is the wordplay.
'part of' indicates the answer is hidden within the clue.
'APHIDS' is hidden in the letters of 'flytrap hid some'.
(Other definitions for aphids that I've seen before include "Small insects like greenfly or blackfly" , "Sucking insects" , "Small plant-sucking insects" , "Garden pests" , "Small insects like greenfly feeding on plants" .)
