Insect damaging to human life, initially (4,4)

Ross

I believe the answer is:

luna moth

'insect' is the definition.
(luna moth is a kind of insect)

'damaging to human life initially' is the wordplay.
'damaging' is an anagram indicator.
'initially' says to take the initial letters.
The first letter of 'life' is 'l'.
'to'+'human'+'l'='tohumanl'
'tohumanl' with letters rearranged gives 'LUNA MOTH'.
