  In predominanly or primevally forested regions like the SE US butterfly
congregation can be enhanced by creating artificial openings in the forest.
In primevally open areas like much of the W US butterflies are attracted to
the edge of bushes or woods. In a dry area they are attracted to moisture.
  Speaking for my own region in Central Texas, we just have to add water to
natural openings in woodland, or add water to bushes planted in open areas
- to enhance our butterfly populations. Butterflies like edges. Give them
