Young insects raised up on pea soup (5)
I believe the answer is:
pupae
'young insects' is the definition.
'pupae' can be an answer for 'insects' (pupa is a kind of insect). I'm not sure about the 'young' bit.
'raised up on pea soup' is the wordplay.
'raised' says the letters should be written in reverse (going up in a down clue).
'up on' becomes 'up' (similar in meaning).
'soup' is an anagram indicator.
'up' reversed gives 'pu'.
'pea' with letters rearranged gives 'pae'.
'pu'+'pae'='PUPAE'
Can you help me to learn more?
(Other definitions for pupae that I've seen before include "Insects in form between larvae and adults" , "Insects in the inactive stage of development" , "Butterflies developing" , "Chrysalids" , "Insects in the stage between larva and adult" .)
