Beetle? from Oahu garden

Beetle? from Oahu garden
Kailua, Honolulu County, Hawaii, USA
February 25, 2009
Size: 2 cm
From my garden. I could not tell what it eats. It prefers to walk and can grasp well, and can fly with an audible buzz.
Is it a beetle? Is it a harmful pest? Is it native to Hawaii?

Beetle? from Oahu garden Beetle? from Oahu garden

Beetle-> Scarabaeidae: Protaetia fusca
pretty sure this is correct - appears worn. Also in Florida now so might be worth adding to the main guide. Commonly called the Asian Mango Beetle. Not native to Hawaii.

Asian Mango Beetle
Thanks for your swift reply. I will check with Hawaiian Ag. Dept., too. Do *I* add to the main guide or does the "web master?" If it is up to me, how do I proceed? By worn do you mean old or roughed up (as by a cat or dog or other insect)? -joe herzog

maybe Protaetia orientalis
Info about P. fusca;
this, this and Hawaii, page 33.
Your specimen is quite shiny suggesting it is an older individual abraded from digging in the soil - common enough. I also only see a hint of the elytral spines.

I just noticed that Oahu has another adventive Protaetia sp. that actually looks like a better fit, must be quite recent - Protaetia orientalis - images

Protaetia orientalis
I'm a little late to this discussion, but I would also say that the scarab pictured is P. orientalis. I don't think this species is officially considered as established in Hawaii, but I see it around (mostly in the Pearl Harbor area) and I think it is becoming more common. On Guam I think it is an Ag pest and also has some conservation concern since it eats flowers of some native trees.

I think you're correct
Now you've got it. My specimen is shiny. I compared P. fusca and Euphoria sepulcralis images to mine -- mine seemed a little different. Mine is shiny and has no elytral spines (I double-checked). Thanks for the help. Now I need to find out if this is a harmful pest.

How do I post images on the "main guide"?

Mahalo, joe

You can't
As I said above Hawaiian images are currently restricted to this section. The main guide is currently restricted to continental US and Canada, but for some reason we keep these images in this side section.

from Hawaii are currently stored here.
