Stump Borer - Derobrachus

Stump Borer - Derobrachus
Tucson, Pima County, Arizona, USA
June 30, 2006
Size: 5 cm
The monsoon has just begun and with it these big guys start flying around. If you're out at night you will get smacked in the head with one, once in awhile - very careless flyers. From the guide I'm guessing either Archodontes or Mallodon. Help please.

Palo Verde Root Borer (Derobrachus hovorei)
While looking through your photos I realized that our Paloverde root borer has changed its name from D. geminatus to D. hovorei

 
Thank you
for the update Margarethe.

Derobrachus sp.
This is one of the three southern AZ sp. of Derobrachus - doesn't look like geminatus

 
thanks
Thanks for the ID. Will now be able to learn a little more about these beasties (or relatives) I see every summer.
