Often referred to as heart-shaped in damselflies. Doesn't look much like it with dragonflies.
No interactions present.
... and more suited to dragonflies, the term "copulation wheel" is sometimes used. The "heart" does seem more appropriate to damselflies, doesn't it?
...isn't a very romantic term though, is it? It's similar to the difference for us between "making love" and "copulating". Though I don't suppose the dragonflies care, as long as they get some ;-).
I don't think romance is an emotion experienced by them.
I must say that, having watched a male Common Hawker smack heavily and noisily into a female Common Hawker that was already ovipositing, rape sprang more to mind than romance.
All the best,
I suppose it might be romantic to a dragonfly. Who knows? Me, I know nothing.
