The buzzati require a drier media than hydei and melanogaster. When I first started trying to culture this fly I put them in the same mix as the others and they did not do well, I think 1 out of 12 cultures actually produced flys. I've used less water in the recent cultures and they are doing much better.
I have been culturing D. buzzatti for a few months now. They seem fairly easy to culture and I like the fact that they get started much faster than hydei. I just use a one to one ratio of media to water and that seems to work well. I have moved most of my frogs over to eating just buzzatti and I like them more than hydei (the buzzatti escape MUCH less.) My lamasi and amazonicus take them well, but froglets cannot quite eat them.
