More Parasite Puppetry

Another parasite, Dicrocoelium dendriticum, which apparently controls an intermediate host in order to get to its ideal host :D.

Zimmer mentioned it, and I found this diagram of its life-cycle, although its effect on the ant is not clear from it. According to Zimmer, it dupes or controls the ant into clinging onto grass blades until eaten by a grazing animal.

Also the Euhaplorchis californiensis causes its fish hosts to jump and faff about, to make them more likely to be consumed by wading birds.

Fantastic. :D
