new southern vt insect

Hi, My mom,who lives in Brattleboro has a new bug in her garden. Unfortunately she does not have a smart phone and I do not have a photo. It is between 1/3 and 1/2 inch long, oval shape,does not fly when disturbed,it borrows into the soil, is reddish-orange with two black stripes that go the length of its body,the stripes curve but do not touch at the center of its back--sort of like this )( . She has never seen them before and wants to know if they are harmful to her garden. I am on the coast south of Boston and can not find any info in any of my books.  Anyone in southern Vermont have any clues?

Hello, I finally got up to Vt. Here is a photo of the bug in question. There seem to be less of them now and I was not able to take a very close up photo. Any clue as to what this is?

I think that's a false milkweed bug.
They're sucking insects that feed on members of the aster family.  A heavy infestation can do some damage to your flowers.

Edit, spelling

Thanks, I looked more images and yes they all look like my bug. My mom will be glad to know that not much harm will be done to her garden. Thanks again
