The Tracker Jackers
Symbolism, Imagery, Allegory
Like the mockingjay, the tracker jacker is another mutant animal that the Capitol has engineered to keep the districts in check. They are a symbol of the Capitol's willingness to do anything – and everything – to maintain their power over ever living creature in Panem. Katniss uses a tracker jacker nest to attack the Career Tributes in Chapter 14.
