Yea I have a habit of just going into the base consept of my ideas.

I have some things I have to do in a little while so I will probably have a better discription for these guys later today.

It's just me, but I think that idea was to give nekos a harpy prey. I may be wrong, but this is what I feel from it. If it was the case, I think a Canari Harpy, or something like that, would have been an appropriate substitute. But, that's only me; that's what their small sizes make me think of.

Well there original concept was to be anti insect companions for faries, The idea of Nekos hunting them is just because of thier size, I could see Neko's hunting alot of prey that small simply because they are part cat.

I'm takeing QM's advice and going into better detail with these guys.

Apperance:
Fairy Banshee's normally stand at 3 inches in hight, like normal banshee's they have webbed wings where arm's should be and large bat ears on top of thier head. They seem to have slightly better eyesight then a normal banshee but they still use echolocation to find thier way around. Thier hair seem's to be darker in color such as black grey or brown.

Behavior:
Fairy Banshee's seem to be very playful like normal faries but like harpies they tend to use insult's in thier language. Like it has been said Fairy banshee's travel in large swarms, Each swarm has a chain of comande there is always a leader that has a small number of trusted 2nd in comande followers incase something where to happen to the original leader it also helps guiding the swarm easier. In some rare cases a real Fairy will be the leader of the swarms. While fairy banshee's get along best with real fairies they also seem to be liked by other predators as they often land on them and clean them of any parasites they may have on thier skin. Individual fairy banshee's all have thier own way of thinking and often want to do what ever they want but in the end they always will listen to the leader who is always the oldest and most experianst in the swarm.

Fairy Banshee's never really give a reason why they only eat insect's because they are perfectly capable of swarming and eating what ever they want as they seem to do this all the time with large insect creatures such as tonorions.

One eye witness told this story

" I was a member of a small groupe of explorers when it happened. we were walking threw the forest of whispers when our scout John came sprenting as hard as he could twords us, we were all very nervouse as John had a look of terror on his face thats when we saw it a Tonorion was chaseing John. We all watched in horrer as the eight eyed monster swallowed our companion then turned tword us. We all turned and ran as hard as we could as we heard the enormouse monster closing in on us, as we ran we eventually entered a clearing as soon as we entered the clearing I heard thousands of clicking sounds, I hapened to look up and see that the entire sky was filled with tiny bat like creatures that moved as a single unite. with out warning the massive swarm began to twist and plumit and came at us. We all instinctivly dove for the ground as the small creatures flew overtop of us. to my surprise they completly ignored us and instead headed twords the tonorion. The tonorion began to panic and tried to run as the swarm hit it in one massive wave, It began to thrash and cry out in pain as the small bat like creatures completly crawled all over it. within minutes there was nothing left of the tonorion at all. Me and the rest of our groupe feared the worst as we were sure we would be next, to our surprise the swarm dispersed and began to fill the sky once more."

I think I covered most of the points if there is something I missed fell free to point it out.
