A new perspective on habitat is presented, which considers the topological relationships among macrohabitats of adults and the sub-set microhabitats of eggs and other juvenile stages. A model of seven topologies is presented using the snail-killing flies (Sciomyzidae: Diptera) as an exemplar; four of these topologies are drawn on a hydrological continuum from aquatic through shoreline to terrestrial, and three are presented as stand-alone specialized feeding groups. Colonisation-extinction dynamics are discussed in relation first to macrohabitat dynamics and then microhabitat structure. The topological perspective has wide application outside the Mollusca-Sciomyzidae taxocene e.g. in parasitoid wasp-host taxocenes, in phytophagous insect-host communities, for freshwater macro-invertebrates and even, in the context of a “landscape of fear”, for bird and mammal populations. The perspective taken is more “autecological” than the traditional “biotope” or resource view of habitats, yet is broad enough to encompass many different behavioural groups as shown for the Sciomyzidae.
