I'm pretty sure this little boy butterfly is a male Barred Yellow because I can see the upper surface of his wing pattern through his wings.

He's sipping nectar from Richardia grandiflora, a very common lawn weed here in South East Florida.

When you're spraying for weeds, keep in mind that nearly every little tiny flowering weed in that lawn is a food source for some adorable little critter like this one.

If we pave and mow everything, and the human race does seem to be trying to, we'll lose these little butterflies, and many more, in the process.

These three pictures are of a much more white little butterfly. I think they're the white  form of the Barred Yellow Butterfly.

The tiny yellow flower the butterfly is drinking from is Broomweed, another common lawn weed in South East Florida, and also a host plant for the Tropical Checkered Skipper Butterfly.

I took these these three pictures in Broward County. All of the others on this page are from Palm Beach County.

This Barred Yellow Butterfly is so small that I'm hesitant to even begin looking for its caterpillar. The Cassius Blue Butterfly is smaller, and I found it's caterpillar, but I knew they were on a bush in my yard so it was easier than searching fields as I suspect I'd have to in order to find this one.
