Touchdown! At Last!

For months, I've been waiting ah, so patiently (well, not always s-o-o-o patiently) for the gulf fritillary butterfly to touch down on our Mexican sunflower, Tithonia. A perfect match, I figured. The showy reddish-orange butterfly (Agraulis...

That's One Beautiful Butterfly

First the lantana, and then the passion flower vine. The Gulf Fritillary butterflies (Agraulis vanillae) flutter daily around our backyard. They stop for a little nectar from lantana (family Verbenaceae), and then head over to the passion flower vines...

The scrub jays are just doing their job. But they're doing it too well. The gulf frittillary butterflies (Agraulis vanillae) are mating and depositing their eggs on our passion flower vines--as we want them to do--but complete metamorphosis always...
