Help finding Ampery

[Nostromo]

I managed to kill 6 out of 7 Amperies but I am not able to find the last one and I havent found any info about the quest anywhere. Help is needed!

after searching the monster fibula in game, i havnt seen anything called a "Amperies" the only thing with the word "ray" that I have found was a blue ray which is in one of the temples.

Those are the mutated flowers tied to that one Basin Keep quest, right? Only thing I remember about it is that they are only on screens where it rains in the Western section of the jungle, and some are a little stashed away, but I don't think any of them were behind any jumping puzzles either.
If you use your Seeker Sense (the little magnifier in your quick menu) you can see some purple diamonds on the edges of the screen where you still have one missing.

There is no help with Seeker Sense/ no clue where to find them.
