Industrious insects (4)

I believe the answer is:

'industrious insects' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for ants that I've seen before include "24 [INSECT] s" , "They live in a formicary" , "Hard workers" , "Inhabitants of a formicary" , "Soldiers" .)

I've seen this clue in the Newsday, The Star Tribune, the USA Today, the LA Times, The Wall Street Journal and The Sun.
