Caenorhabditis drosophilae
Caenorhabditis drosophilae is a species of nematodes. It was recovered, along with Rhabditis sonorae, from saguaro cactus rot in Arizona. The species was found on the fly Drosophila nigrospiracula.
C. drosophilae forms a Drosophilae supergroup with other Caenorhabditis species. This supergroup gathers species associated with rotten cactus or fruit and Drosophila species. It opposes the elegans supergroup where C. elegans stands.
