Not sure what kind this one is, but think it's similar to the morning glory. Got out late this afternoon after the rain and needed the flash the get a shot. Did get an insect, which is on the very top of the flower.
This is a very pretty flower. I have something for you to try next time. Instead of flash, set up on tripod do a longer exposure and use flashlight with coffee filter over it , to paint the flower , and some of the leaves, paint the flower more than the leaves and leave edges dark. No wind and still flower will be a must. Keep flashlight moving in small bouncing or jiggling motions so light doesn't settle into a bright spot. Let me know how it goes.
