Does anyone know how bad this has spread here in Florida?

http://mgonline.com/articles/citrus_gre ... sease.aspx

I have two wild lime bushes and another citrus bush of some kind (not sure what it is). If any of those plants can be infected, I am wondering if the beautiful Giant Swallowtails could become extinct because of the citrus diseases? Is there another non-citrus plant that GST use? Do they use Rue as a host plant?

Yes, Giant Swallowtails DO use other host plants in addition to the citrus plants that you speak of! Although I have several citrus trees in my yard, I have found that the GSTs like my Rue plants better! There are a number of plants in the 'citrus' family that can be hosts to these beauties. So, don't worry. I mean, yes, DO worry about this horrid situation but the butterflies can utilize other plants, too.

I see that it is spread by 2 different insects and has recently been found in CA.

Looks like the USDA has setup this website to spread info:

Thanks for the idea to use Rue.

And thanks for that USDA website link. I hope they are able to stop this terrible citrus disease. I love to eat oranges!

I sure hope something is done about the problem, too! I've got a big orange tree in the back corner of my garden and a smaller satsuma that I planted last year. Giants have been scarce this year, but I finally got some eggs, which have just now started hatching. I'm raising them on rue and wafer ash/hops tree/Ptelea trifoliata, another member of the citrus family that they love.

Heard from the wife of a man whose job is a citrus broker and he said that this disease is a major concern for the citrus industry here in Florida. I guess I need to get some seeds for Rue and try growing those. I have wild lime and another non-fruit bearing citrus plant, but have never seen the Giant Swallowtails using either as a host plant.

I'm now rearing more giant swallowtail caterpillars than I can count, including two big ones that look like they're about to pupate. The Mama - assuming there's just one - has laid her eggs a few at the time over a long period. I saw her laying one today on some rue in my front yard, but she's used my Ptelea trifoliata/hops tree, rue, orange tree, and satsuma tree. I have a lot of rue, so I'm transferring most of the cats to the rue.

They're fun caterpillars to raise!

Sherry - That is awesome! Do take some photos if you can and post them. I'd love to see your caterpillars!

Okay, Becky! Never ask a caterpillar person to show pictures of her babies, because you'll surely be sorry you asked!

Here's a picture I just took of two of the little giant swallowtail caterpillars -



And here's a picture I took the other day of a mid-instar cat -



And here's a picture of a late instar caterpillar, probably about to pupate. Have you seen pictures of organ grinder monkeys with what looks like a chauffeur's cap on? That's what giant swallowtail cats look like to me -

Sherry - Thank you so much for posting those photos! You got some great shots of the Giant Swallowtail butterfly caterpillars!

I raised a few 2 years ago, but I don't usually find cats in my yard. I don't know if the wasps get them before I find them or the butterflies just aren't laying eggs on any of my plants. I need to get a Rue plant for sure! I love those huge butterflies! I wonder if they are the largest North American butterfly?
