What is this pollen harvesting beetle?

Rosecandy VA, zone 7June 13, 2014

Last year I saw this beetle on my Midnight Blue roses. It was litterally cutting down the stamens as if it was collecting them for their pollen. To my knowledge it did no damage to the leaves, petals, or pistol. I didn't think to take a picture of it then, but today I saw it on my mother's daylilies and I was wondering if it might be a beneficial bug (hopefully one that eats thrips, as we are infested with them!). Does anyone know what it is and what it eats? If it's not harmful I plan to leave it alone.

Cucumber Beetle - they only eat the rose stamens. Annoying things. It will damage the foliage of Cucurbits in your garden, but won't likely bother the roses except for the stamens.

Looks like a Spotted Cucumber Beetle...
I have little knowledge on their habits though.

I have known the SCB to nibble on petals, but not a big deal. They are hard to catch!

I get these every year too. I do notice some damage but it never seems to be that much so I ignore them.

Okay, so they aren't a problem for me then. Thanks everyone!

I have wondered about these so did a little search. From Wikipedia:

In the adult form, it eats and damages leaves of many crops, including cucumbers, soybeans, cotton, beans, and many others. In the larval form, which is known as the southern corn rootworm, it tunnels through the roots of young plants, stunting or killing them. These native pests have a wide range of host plants, but will readily infest a field of crop plants, most notoriously corn.
