Ornateops

Feel free to critique this idea, all feedback is appreciated if it helps me make an interesting scp

+ The Concept

This scp is a group of 4 warble flies , for those who don't know one species of fly that lay larvae in animals. They speak random words from time to time and don't respond to verbal or visual indicators. When any lays it's larvae in a human the larvae will move to areas near the brain. Hosts of the larvae Report hearing whispers in their heads, occasionally stringing together events of the hosts life. Once the larvae leave the body, sometimes killing the hosts, they can speak fully and retain memories and thoughts of the host by speaking them.

Possibly they could be more agressive In mating seasons or even cause memetic effects like from hearing their words for a long period of time

I want to make this more than a talking animal scp so I will most likely add addenda in the draft to make a bigger mystery behind it.

My current questions are:
Has this been done before/is it too similar too another scp
Is there anyway I may improve this idea
Is this too cliche

I feel that this will sound much better in a draft and after the addenda and I'm thinking up lore for it so feel free to leave any questions as I will put this all in the draft later, thanks for any critiques.
