Sphaeroderus stenostomus

Sphaeroderus stenostomus

When I put this in the petri dish it shot a thick stream of dark colored fluid. Kind of a shocking amount with a reach of around six inches or more.

Moved from Sphaeroderus nitidicollis.

Thanks Curt!

This is S. stenostomus lecontei.
The smooth, distinct convexivity between basal impressions of pronotum and lateral bead eliminate nitidi*collis as a possibility. Nitidi*collis also usually has a less constricted head behind the eyes and much more interruption/irregularity of elytral striae.

Awesome behavioral note, by the way!
