Bug archival supply? (5)
I believe the answer is:
larva
This clue might be a double definition.
'bug' is the first definition.
(thesaurus)
'archival supply?' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
Can you help me to learn more?
(Other definitions for larva that I've seen before include "Immature form of (insect) development" , "Juvenile form of insect" , "early form" , "Insect's immature form" , "Volcanic outpouring" .)
