Hi Rachel! From the information I can find find these are hard to tell apart on morphology only. From my guide (Simpson and Day 6th edition): Yellow-spotted has different calls and flight mannerisms. Graceful is more energetic. Both occur in the same habitat which doesn't help. Graceful is said to have a "more slender body".
