Does trichomycete symbiosis with flies (Diptera) follow host phylogeny?

Trichomycete fungi are obligate symbiotes in the hindguts and midguts of many aquatic fly larvae. Some species occur in multiple host species, and some are limited on a host-family level. Some hosts are mysteriously devoid of trichomycetes, such as mosquitoes, which lack midgut trichomycetes. We asked whether the current dipteran phylogeny reflects presence and absence of trichomycetes in hosts. No host phylogenetic pattern was evident other than greater representation in the Culicomorpha. Aquatic larvae that are predominately filter feeders or grazers are used as hosts; predators are not. Midgut trichomycetes occur more commonly in lotic hosts, except for chironomids. Some expected hosts, such as Deuterophlebiidae, have not been explored yet.
