What kind of Beetle? - Pycnoscelus surinamensis

What kind of Beetle? - Pycnoscelus surinamensis

Since I found this in the sand under a patio stone, I'm thinking it is a ground beetle but I cannot find it in the guide anywhere.

and a handsome one at that. Possibly Pycnoscelus surinamensis.

That was quick! I just got done adding the second photo! Thank you so much. Roach, ick!

I can confirm Jim's ID
- if you look on the info page you'll see that the pale front edge of the pronotum (behind the head) is characteristic of this species.

Thank you Hannah
I did look at the page after I found out it was a roach and not a beetle. Boy, do I feel dumb.

Nice image
Nice image, as always, Carla. No need to feel dumb. The great thing about BugGuide is we're all learning so much.

One thing that you'll almost always see in a beetle picture is a perfectly straight line down the back where the two elytra (wing covers) meet.

I say almost always, because rarely it may be hard to see, or it may be a wingless female. I just got through printing a photograph of a Warty Leaf Beetle where the suture (the line where the elytra meet) was straight for half its length, then changed to a serrated zigzag pattern.

But still, in 99% percent of beetle photos, look for that straight suture in the middle of the back.

I enjoyed looking at your other images. The Burrowing Owls are priceless!

Thank you
Thank you Stephen for how to tell beetles from roaches and for your nice comments about my photos. I also love the Owls. To think, I was 3 feet from them laying on the ground. :-)
