Insects were collected via pitfall trapping (mid-June 2006 to mid-August 2006) in a 400m X400m plot within the San Juan Mountains of Colorado. The site is located just south of Sultan Creek and east of Highway 550 in San Juan County at an elevation around 10,400ft. The area is characterized by gentle ridges and valleys oriented in a north-south direction. An ongoing taxonomic list and general biodiversity of the insects that are found in this area will be presented. This study is part of a larger project investigating how geographical, geological, and soil factors are possibly influencing abundance and diversity of ground-dwelling insects occurring in the San Juan Mountains. So far this research project is the first of its kind studying ground dwelling insects in this particular geographical area.
