conspecifie densities due to higher probabilities of locating suitable mates there. Specifically, males would likely be attracted to areas of high female density, (Hanski et al. 1994, Kuussaari 1998). The second argument was given by Gilbert and Singer (1973), who argued that a high density of butterflies in an area, especially of the same species, could be an indicator for suitable habitat. Therefore, an area with high conspecifie density would trigger emigration from areas with low conspecifie density as new adults would view the high density of same-species as a sign of suitable habitat, perhaps containing ample resources such as water, nectar, and host plants. Positively density-dependent dispersal On the other hand, there are also arguments supporting positively density-dependent dispersal, which is when individuals disperse at higher rates away from areas exhibiting high conspecifie density (Dethier & MacArthur 1964; Odendaal et al. 1989; Baguette et al. 1996, 1998). These supporting arguments most often have to do with social interactions within the patch (Shapiro 1970; Odendaal et al. 1985, 1989; Baguette et al. 1996, 1998). For instance, in some species of butterflies, males will vigorously pursue females in order to mate with them. While this may be effective for males that are pursuing un-mated females, sometimes the females have already mated and are reluctant to mate again. This does not often dissuade the males, as studies have observed them harassing females to the point of the female leaving the patch (Odendaal et al. 1985). Should this happen frequently and repeatedly, a likely scenario in a high density population, the result would be a high dispersal rate away from the area by females. This, in turn, could trigger a similar dispersal pattern among males that may then leave the area too, in pursuit of females or in search of an area with more females (Baguette et al. 1998). A high conspecifie density in a particular patch may also directly affect habitat quality of the patch, which could lead to higher emigration rates should the patch' s density surpass the
