<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">group of bees</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for swarm that I've seen before include "Plague of insects" , "Find insect population" , "Body of bees" , "Mob" , "Mass of bees" .)
