The wildflowers are in full bloom here and begging to be photographed.

Many are bold and brilliant.

Others, like this Phaseolus vine climbing on a saguaro, are more subtle.

These plants are related to tepary beans and string beans.

The flowers have an interesting structure and it made me curious about what pollinates them.

Looking it up, it turns out that beans, etc. are self-pollinating.

Does this flower fly know that?

Or maybe it just wants to be pretty on pink.
