The Cayman crab fly revisited--phylogeny and biology of Drosophila endobranchia.

<h4>Background</h4>The majority of all known drosophilid flies feed on microbes. The wide spread of microorganisms consequently mean that drosophilids also can be found on a broad range of substrates. One of the more peculiar types of habitat is shown by three species of flies that have...

Furthermore we also provide additional data on the behavior of these remarkable flies.<h4>Conclusion</h4>Our findings reveal that the two Caribbean crab flies are not as distantly related as first thought, as both species are members of the derived repleta radiation. That this lineage has given rise to two species with the same odd type of breeding substrate is curious and prompts the question of what aspects of their shared ancestry has made these flies suitable for a life on (and inside) land crabs.
