The GSTs out here mainly use the citrus trees. They seem to prefer tangerine over grapefruit in my yard but at the ranch they prefer the orange trees over the lime, lemon and grapefruit trees. Once in a while I'll have cats on the rue - which I keep in my yard for the Black Swallowtails too.
Also out at the ranch they use native Colima (prickly lime ash) and barretta (torchwood). It's always nice to see those big butterflies flitting around :o)
I love to see them puddling too.
