Butterfly populations are not only influenced by climate, habitat conditions, and other site specific variables, they are also influenced by direct harm. Butterfly conservation in this park and elsewhere will help ensure the continued enjoyment of these fascinating creatures. Unfortunately, Death Valley National Park has had large-scale illegal commercial butterfly collectors in the past. Some have been caught, sentenced to jail, and have faced stiff fines. Remember, specimen collecting within the park, for personal or commercial use, is prohibited, unless it is part of an approved research project and in possession of a valid National Park Service research permit. Handling butterflies or other wildlife is also not permitted. Butterflies in the park are best appreciated with the aid of binoculars or a camera. Please do not use nets or other capturing devices.
