Not an emerald ash borer — but what is it?


Emerald green beetle, looks a lot like a longhorn.  I feared it to be a dreaded emerald ash borer, but it’s not.

Okay.  What is it?  Any body know?

From our Backyard Collection, two weeks ago:

What is this one? Looks like a longhorn beetle, emerald green.

What is this one? Looks like a longhorn beetle, emerald green. Not an emerald ash borer. Anyone know?

It’s too big to be an emerald ash borer.

Our mystery beetle is too big to be an emerald ash borer.

Perhaps a flower longhorn beetle?

Where’s Bug Girl when we need her?  (Moving?)  Roused Bear? Beetles in the Bush?

Update, mystery solved:  Ted C. MacRae said (see comments) it’s the bumelia borer (Plinthocoelium suaveolens).  He wrote about it here. So, Kathryn, what are they eating in our backyard? Bumelia lanuginosa is a Texas native; do we have one, or a relative, in the garden?  Dallas-area Dirt Doctor Howard Garrett says they’re mostly harmless in the garden.  (Here’s a closeup, from MacRae’s blog):

    Maybe walking stick next; maybe butterflies, or moths. Or ladybugs.

    Read the headline, skip the post.

    Thanks for dropping over to identify. Are these supposed to be common around Dallas? My wife found several of them in a recent project.

  5. You’re right – it is a longhorned beetle and not an emerald ash borer. This is the bumelia borer (Plinthocoelium suaveolens), what I consider to be Notth America’s most beautiful longhorned beetle. I wrote about it on my blog using that as the title. Very nice find!
