Dad turned round and concealed insect attacking roses (5)
I believe the answer is:
aphid
'insect attacking roses' is the definition.
I can't judge whether this definition defines the answer.
'dad turned round and concealed' is the wordplay.
'dad' becomes 'pa' (both can mean one's father).
'turned round' says the letters should be written backwards.
'and' says to put letters next to each other.
'concealed' becomes 'hid' ('hide' can be a synonym of 'conceal').
'pa' in reverse letter order is 'ap'.
'ap'+'hid'='APHID'
Can you help me to learn more?
(Other definitions for aphid that I've seen before include "Small plant-sucking insect" , "Plant louse" , "Small insect like greenfly" , "Horticultural pest" , "Fly" .)
