HI Bugman,
We planted Cape Plumbago to attract these little butterflies. Marine Blues have been the most difficult butterflies to photograph and I have not been able to get pics of anything but adults. They almost never rest and flit around my yard about 2 feet off the ground. If two meet, they spiral together about 15 feet up in the air.
These first photos were taken in 2011.

Hi Jeff,
Thanks for resending these images.  We agree that they represent the Marine Blue.  According to BugGuide:  “Caterpillar hosts: Leadwort (
Plumbago) and many legumes including alfalfa (Medicago sativa), milkvetch (Astragalus), and mesquite (Prosopis).”  Having the plumbago in your yard is providing food for both adults and caterpillars.
