tdogmom - I guess you could call any Papilionidae that use Artistolochia a Pipevine Swallowtail. And that includes a big bunch of them if you consider the world genera of Papilionidae that do use that group of plants. That would would include many of the tropical Graphium species from North, Central and South America, the South Pacific, Eurasia, Africa, etc for example. Susan - That would be a massive list to assemble even just for the lepidoptera that are or could be encountered in North America, especially if you include all of the Macrolepidoptera, Microlepidoptera, their species, subspecies, forms, races and aberrations and the synonyms. Hundreds if not thousands of books already have those lists and IMO if anyone wants to take the next step it would start with buying one of the few good books already out there. I say few because all are not created equal and depend on how an author interpret's known data. Unfortunately some of the best are long out of print even though they are not up to date with the changes in taxonomy since they were written. Have to cut this short... son just showed up for a days visit. I'll be back with some comments on Battus.

Sure are a lot of "dorfus'" here - meet Dorfus Burger-Head here!! Wow that doesn't sound too smart does it. Oh well, this is fun.

I use a product called Callex. It comes in a small jar and I order several jars at once from Amazon. I believe it is also sold at CVS, etc.. It was recommended to me by a coworker who was told by her podiatrist about it. It is the consistency of Vaseline. I put it on at night with socks. It works really well to keep my heels smooth.

It doesn't have to be the night before. The crystals build up which is what causes the pain. I don't drink either, for me it is the veggies I eat. I had 5 shrimp the week before, ate pureed cauliflower, ate a bunch of asparagus during the same week and a package of mushrooms. My Doctor told me I just have chronic high uric acid in my blood as does my sister. Before I was diagnosed years ago I went to the Doctor because I thought I had skin cancer. I had these black crusty round spots on the top of my left thigh. I think my Doctor called it tophi or something like that. They finally went away after I started taking the medication. My uric acid level at that time was so high I had 2 Doctors call me after I had the blood test to come back in right away.
