and phylogeny in the planitibia subgroup of Hawaiian Drosophila.
If the two taxa being compared already have complete reproductive (i.e., genetic) isolation between them, then the significance of any ethological isolation observed is equivocal since they are already genetically isolated lineages.
A one-way bias in ethological isolation, where barriers to pollen flow between the two species are not symmetrical, has also been observed in the relationship between Bombus and Rhinanthus (Kwak, 1978).

The effects of founder-flush cycles on ethological isolation
in laboratory populations of Drosophila.
and the phylogeny in the planitibia subgroup of Hawaiian Drosophila.
Changes in mating behavior produced by selection for ethological isolation between ebony and vestigial mutants of Drosophila melanogaster.
Selection for and against ethological isolation between Drosophila pseudoobscura and Drosophila persimilis.
Hawaiian Drosophila are a favorable subject for studies on the genetic mechanisms underlying ethological isolation
(Carson 1978; Kaneshiro 1989).
The results of our experiments, which attempt to model Carson's founder-flush-crash theory to the extent feasible, may then be seen as supporting Carson's model to the extent that they show that the conditions of the model may lead to the evolution of ethological isolation
. However, significant ethological isolation
between individual populations is observed in only a few of the very many cases tested, although in a few more than is expected by chance; and, with one exception, ethological isolation
between particular populations does not persist through the various cycles.
