This time, I used high speed continuous mode and I din't stop until 20 frames, then checked & all are good shots but only two are synchronised . One advantage with this act is normally it will not get disturbed quickly and will give sufficient time to think.

What was the shutter-speed? I read about this feed & bleed behavior of butterfly in the book (Paschembanger Prajapati) by Shri Judhajit Dasgupta.

The jets are continuous for every second, that means the sucking is so fast.
