Ecological notes.

This species was collected in the natural habitat of mountains and valleys covered with variety of vegetation, sand, and stones. Species was distributed in elevation ranging from 892-1611 m (Fig. 49). Adult beetles were attracted to UV–light. In winters this species appears in low elevation while in summers it appears in high elevation.
