    \noindent{\bold Individual Trial Voronoi Diagrams}

    The ant\-lions were studied in several different (restricted) container sizes.
    These Voronoi diagrams which label the territories of each ant\-lion (an ant\-lion ``possesses'' a part of the map within its segmented portion if its pit (the blue dot) is closest to that point).
    By examination of the Voronoi diagrams in conjunction with measurement of the closest neighboring pit, it was determined that ant\-lions reclude and cannibalize sufficiently to ensure roughly constant habitation density (proving, at least evolutionary, awareness of group strategies like allowing a few ant\-lions to become adults very quickly).

    \noindent{\bold Trial and subtrial Voronoi Diagrams}
    Two trial sizes were tested twice (earlier on left, later on right) because the ant\-lions submerged themsel\-ves in the sand and became inaccessible.
    This shows that, when given appropriate time to develop new nursery conditions, ant\-lions manage to successfully redistribute themselves.
    In the wild, this would correspond to a number becoming full adults and the remaining larvae rising to the surface.
    This indicates that they have advanced detective capability, likely without complex group-interactive cognition
