So there they were, the bride and groom, culminating their vows.

We spotted them in Vacaville, Calif., clinging to a passion flower vine (Passiflora), their host plant--just the two of them, the female Gulf Fritillary (Agraulis vanillae) and the male.

Two's company? Not for long.

Soon other Gulf Frits descended on them.

Two's company, three's a crowd. Where did all those uninvited guests come from? They're everywhere!

All went well, though. The guests fluttered off, leaving the couple alone and allowing the photographer to engage in insect wedding photography.

Gulf Frits are incredibly beautiful, what with their bright orange wings with black markings, and underside, their elongated silver iridescence spots.  A touch of the tropics!

Gulf Frits have been around a long time in the Bay Area--more than a century, according to Art Shapiro, distinguished professor of evolution and ecology at UC Davis. "This dazzling bit of the New World Tropics was introduced into southern California in the 19th century--we don't know how--and was first recorded in the Bay Area before 1908, though it seems to have become established there only in the 1950s," Shapiro writes  on his website. "It can be quite common in the East and South Bay--particularly in Berkeley--and has been found breeding spontaneously as far inland as Fairfield, where, however, it is not established."

"There are scattered records in the Central Valley and even up to Folsom, perhaps resulting from people breeding the species for amusement or to release at social occasions. According to Hal Michael, who grew up in South Sacramento, this species bred there in abundance on garden Passiflora in the early 1960s. It seems to have died out by the early 1970s, however. Intolerant of hard freezes, it still managed to survive the record cold snap of 1990 that largely exterminated the Buckeye regionally!"

Shapiro says that in the Bay Area "this species can be seen flying any day of the year, if it is warm and sunny enough."

Thankfully, that's not all they do.

Coming soon to a passion flower vine near you--eggs, caterpillars, chrysalids, and then those gorgeous butterflies!
