I'm not an expert by any means, but I think you are correct. Although many people confuse the two, there are differences, the most apparent being that the damselfly has a more slender body and tends to hold its wings together, whereas the dragonfly usually holds its wings open horizontally. The damselfly's eyes are much farther apart than those of the dragonfly.
Both beautiful creatures though!

I think damselflies are prettier!

He is a predator :D :D
