Carol, you can get the blackworms in 2 places. One is direct from Australia and one from his new supplier in the states. The ones in the states are a bit more expensive (couple of dollars), but they will get to your house faster then ordering from Australia. Prices look high, but the quality of this food and the way the fish take to it to me is worth it. To some its not.

Bah, you lucky Australians! Well...it only cost me $10 to ship a large order of them from Australia so I can't complain. I'm in love with the food personally...the fish love it and that's the only thing I'm feeding. Seems to really be a good complete food. The pair is breeding every week as well.
Ah, but they are. However Pigeon Blood is the main strain, what this strain descended from and a general description/classification. White Butterfly is the actual strain name...just Pigeon Blood based. If that makes sense. They've been bred over the many years to bring out a very clean white fish out of the original orange/white PB strain and this is what the result is. Check out the link in my signature, Common Discus Strains & Abbreviations. Shows you the wide variety of colors, patterns, and strains. Many of those are Pigeon Blood based.
