They're the guards of the blue Ynts. (They're just as blue, their purple-green coloring probably is just some sort of natural warning-color while they're on duty. o8-) )

Most dutiful they fly their small guarding pathes, snapping and hissing dangerously (and very loudly). They're really not to kid with! They also have spikes on their backs, so don't even try to butt-bounce them. Best thing is to try to sneak through inbetween, there ARE small gaps.

They guard the most important parts of their community, of course - Ynt Death Garden, Ynt Weeds and Ynt Eggs.
