Nice beetle that jumped on me.
Thanks Bayucca!
Another Brentid mimic identified - from Asia:

I could imagine, that resemblance is enhanced by mode of walk.
If I recall right, Brentids walk rather stalky, their tail waving a bit.
Very interesting, when I saw this guy it reminded me of a brentid I saw in South America. http://www.projectnoah.org/spottings/254...
It is just a theory of mine - I think, it has not been suggested yet, that Brentids serve as mimicry models. But resemblance there is. A case from Asia:
Brentid (common colour pattern in larger species in that region):

Longhorn (note first two antennals broadened, and how antennae are displayed):

Possible advantage: Brentids are very armoured insects; small birds will not be capable to crack them, if they are too big to swallow. I guess, birds will learn not to waste their time.
In Central America, a yellow stripe pattern is common in Brentids:

Thaptor and Bayucca, what advantajes would there be to mimic a brentid beetle? thanks
Hi , bayucca - I took this as a perfect ID. Cross-checked it, now I say: It already was :-)
Nice it does look like a Cerambycidae, only I'm really really new on this so I thought Cerambycidae where bigger, thanks for the info!!
Cerambycidae, Cerambycinae, Platyarthrini, Platyarthron semivittatum.
