Blochmannia is a genus of symbiotic bacteria found in carpenter ant. There are over 1000 species of these ants and, as of 2014, of the over 30 species of carpenter ant that have been investigated, all contain some form of Blochmannia. The bacteria filled cells currently known as members of the genus Blochmannia were first discovered by zoologist F. Blochmann in the ovaries and midguts of insects in the 1880s. In 2000 Candidatus Blochmannia was proposed as its own genus.
