One point about insect wedding photography is that you don't need an invitation to attend. You just have to keep your distance and not disturb the bridal couple.  No sudden movements. No stressful impatience. And no camera flash, please.

It helps, though, if you grow the host plant so a bride and a groom will show up. In this case, we grew passionflower vine (Passiflora), the host plant of the Gulf Fritillaries (Agraulis vanillae).

One morning we saw a butterfly eclose from her chrysalis. Wedding Day! Within minutes, a male suitor arrived.

They became a couple.

Then unexpected guests arrived...a hungry caterpillar munching on the leaves and a second prospective suitor (PS) (rejected) and a third PS (rejected) and a fourth PS (rejected).

PS, leave them alone!

When the "ceremony" ended, the couple simply left. One sipped nectar from the nearby Mexican sunflower, Tithonia rotundifola. The other flew over the fence.

Soon we'll have more eggs, more caterpillars, more chrysalids, and more adults. 

Life is like that when you're growing Passiflora and hoping for a Wedding Day.
