need to work on managing space in butterfly guard, dont forget to put feet on hips but make sure to grip fight to stop grips on legs at the same time
additionally, I am wary of feet on the hip as that could turn into a ankle lock, heel hook opportunity depending on foot positioning
yes in butterfly you have to have hooks on the inside of opponents(O) thighs. But when managing space, for example to set up arm drags or just to keep O from pressuring you you need to be able to put feet on hips momentarily to stop O's advance. expand for examples.
