What geographic demarcation line is noted as centering the densest cluster of confirmed stag beetle sightings and biological studies?
Answer
States east of the 100th meridian
When analyzed geographically by plotting confirmed sightings and scientific studies, the primary concentration of stag beetle activity centers significantly to the east of a major longitudinal marker. This area, defined as states located east of the 100th meridian, corresponds closely with regions that historically supported extensive deciduous forests. The prevalence and density of these beetles noticeably diminish west of this line, particularly in areas like the Rocky Mountain states and the far Southwest, which are generally characterized by less favorable habitat conditions compared to the dense hardwood forests further east.
