Blue-margined Ground Beetle

Pasimachus elongatus/ Pasimachus depressus

Description:

There were several of these scurrying across the dirt road. All going the same direction! (odd....) They are FAST! They have some wicked-looking mandibles that this fellow that I managed to catch didn't seem afraid to use. The thorax has a little rolled-up rim around the edges, all surfaces are smooth, and very shiny. Eyes are on the very edges of the head, and can be seen in the photo.

Habitat:

Transition zone between scrub and oak hammock. (More scrubby than hammocky).

Notes:

I have found conflicting information about what these critters eat. Most sites I have found say they are carnivorous (which makes sense, considering how fast they can run...), but a few say they are either omnivorous, or vegetarian. Anyone able to give me more specific advice?

Well, I have found that my beetle is definitely carnivorous . He (?) is chewing down on a mealworm at this moment.

I will. I'm using the app right now, and your link doesn't seem to work on it. I'll try it on my laptop tomorrow. :)
