They started out using plumbago as a larval host in my front yard and but found the Least Snout Bean Vine (Rhynchosia minima) in my back yard. The LSBV is abundant in my back yard and so are the Cassius Blues!

TINY! You almost don't even notice this butterfly as it flits about. You'll think it's one of those white moths that come up out of the grass but if you stop and might be this Blue.They're social, so if it does stop you'll be able to get close enough to id it.They love my powderpuff tree for nectar and they lay their eggs on the native FL plumbago.

Abundant in South Florida. These teeny tiny little guys (.75-1") thrive in my yard. They love Plumbago and weedy wildflowers. Once in awhile you catch a glimpse of the beautiful blue on the dorsal but to get a photograph is nearly impossible. They are constantly on the move.
