The Invasive Arzuros is the main target monster needed to progress the game, it will be marked on the Blessing Hills south of the Canalta Timberland area during the Ward mission.

The key to repeling the Invasive Arzuros is to make it run out of honey. However, its main moveset cannot be prevented easily. Since the Arzuros requires honey to summon new Arzuros, eliminating them and making the Invasive Arzuros summon new smaller Arzuros will cause it to run out of Honey mid-fight.

The Canyne Egg is your main reward for repelling the Invasive Arzuros. It will be hatched after you return to Sheparden and progress the story.
