Due to fact they're so tiny, they're really difficult to hit

So it's offer a pretty decent distraction, for wilds creature you're killing

But be aware they're low in health, stamina and damage, so pump these stats

And pump the speed as well ;

it would stuck less behind walls or trees, it would be harder to hit, for both wild and PvP opponents

With higher speed big fly-bug, you'd be protected from larger perimeter, so needs less of them

And the last, but not least interest to upgrade his speed it would increase the amount of food his using by himself, and so it would automatically increase his health regeneration
