Brian, despite making a number of online searches, I haven't been able to determine that Citrus is a host of SLF. As I also reside in the affected area, I have been keeping a close eye on the nymphs this spring. To this point, although there are incidental SLFs on the Citrus, I am uncertain that they're feeding on Citrus.
Pecan, nightshade, apple, grapes, and especially tree of heaven are magnets for SLF.
