The Butterflies of Howard County, Maryland. A Biological Summary and Checklist
In addition to entertaining us with their bright colors and interesting life histories, butterflies serve as easily observed indicators of the biotic diversity and the true degree of unaltered natural environment retained in local areas. This is due to their attachment to an array of specialized host plants and to their notable sensitivity to environmental disturbances and introduced chemical agents during the larval stage. Thus, the variety of butterfly species obtained from a local survey and photographic record can contribute to an environmental understanding, and the survey and photographic activity can offer a pleasant pastime and beautiful photo-record for sunny spring and summer days spent outdoors.
