Some popular variety grub (5)

I believe the answer is:

larva

'grub' is the definition.
(thesaurus)

'some popular variety' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'LARVA' can be found hidden inside 'popular variety'.

(Other definitions for larva that I've seen before include "shows form of immaturity" , "Immature form of (insect) development" , "Volcanic outpouring" , "Wriggler" , "Tadpole or caterpillar, say" .)

I've seen this clue in The Telegraph.
