Humans and other animals use the global geometry of the surrounding environment in order to orient and determine which direction they are facing. Accordingly, the impact of environment geometry on spatial behavior is reflected in the paths of progression in the environment. When the perception of the global geometry is limited, such as in large or dark environments, the global geometry of the environment has to be constructed gradually as the accumulated geometry of locales.

We report here on two complementary experiments examining the effect of climate on morphological and life-history traits of antlion adults. We first examined whether body size and wing loading of emerging adults are plastic by raising larvae, collected from five antlion populations along Israel's sharp climatic gradient, in two environmental chambers simulating temperature and humidity of desert and Mediterranean climates. The variance in adult morphology was mostly related to body size, with adults of Mediterranean populations being larger than those of desert populations.
