This is a hard call as far as positive or negative...the adults feed on grapevines and possibly the fruit...thus, making them a pest...the larvae feed on decaying wood and stumps, making them a useful creature.

This golden-yellow Scarab is found throughout eastern North America...south to FL. , and west to Nebraska. Found mainly in deciduous forests and surrounding areas. Adults are attracted to lights at night. They are most often seen May through August.

One of the many May/June Bugs found in this part of the country.

I found one of these today on the screen of my garage window. I'd never seen one before and was wondering if this is the critter that's been trying to eat my plants. I'm relieved to learn that he is not my culprit. Some nearby neighbors have a grape arbor.

I've noticed this beetle on our window screens at night several times. We have wild grape vines in the pasture, not sure if that's where it's coming from. Dug one up when taking out an old stump. So far, never observed it doing damage to any plants.

Saw one of these today. It was rather large, about 1.5" long. I noticed it right away because of it's spots, and sheer size. I've never seen one of these before, however the small brown "June bugs" (no spots) are common here. I'm not aware of any grape vines in the immediate vicinity.

I found this huge beetle on a climbing rose... I'm not at all happy to have another critter gnawing on my roses!

My next door neighbor grows masses of grapes, so these are a common sight in my neighborhood. I never actually made the connection until this year, though. Go figure.

I don't have any grapevines, but read that the larvae eat rotting wood (which I have lots of). Surprising to see him - it's my first time with one of these. It was missing a portion of leg, so I took it indoors to photograph it and forgot him for near two days. I thought it had died, but when I took it out of the shallow cup I had kept him in, it livened back up and was crawling all over me. Not vicious at all and very interesting to look at. I sent it back outside to live peacefully.

I was excited and a little fearful of this bug at first. But when the flash went off, I figured he must not be a crazy bug like the "june" beetles that I'm used to that are about 1/3-1/4 this guys size. If I ever see this guy again, I will put him in a bug cage to study him a bit more. Awesome looking guy! My daughter will love looking at him. If I kept him in a wire cage, do I just need to give him grape leaves to eat until I release him? It would only be a day or two.

We just found three while breaking up a rotting length of maple trunk (tree was cut five years ago and laid at the edge of the yard.) Pretty cool beetles- they seemed to have just finished pupation and were very soft but had the distinctive spots. We do have wild grapevines nearby.

My son found this on our porch tonight. Used to seeing dobeson flies as we live beside a river....but it was a grapevine beetle instead. There's been alot of these in this area this WEEK! Do they migrate? This one was a good inch long if not a bit more. We let it go after a short NO FLASH photo shoot. There are woods out back as well with several fallen trees from a tornado that came thru here June 1 2011.

I found this large beetle on a Clethera bush today. It wasn't eating, just sitting there. I'm in Upper Bucks Co.Pa and have never seen one of these before. There are a few old grape vines growing randomly in the woods so maybe that's what it was looking for.

Found this bug outside. My husband said something bit me! And then we saw this big guy. Never seen one before. Put him in a bug jar inside and took pics. He seems quite aggressive. I think he may have just latched on and pinched him though while climbing. It looks like a giant lady bug. Quite interesting.

We live in suburban Minneapolis (MN) and my wife called me over to our grapevine trellis today.

Here was a "fine looking" fellow whose size set him apart, and then his proximity to our grapevines further concerned us.

Thanks for having a clear image for us to compare.

Though I'm impressed with her/him and admire her/his "beauty" there will be no return trip to the trellis.

We will submit a photo with a U.S. quarter coin for size comparison.

Came into the house the other night with it on my shirt. Excited to see it, put in bug cage for the kids to examine it. My son called it a giant ladybug. After 2 nights we let it go in the front yard. Had it crawling on my hand and my son's as well. A good learning experience for my kids and pretty cool to see something you don't see too often here. We live in the country with farm cropping all around us; so I use every opportunity to expand their world. Good to learn before exterminating out of fear. He wanted to keep it for a pet.....don't know how mom would have been with that!

I live in the town of Westerleigh in Staten Island NY, one of the five boroughs of New York City. My daughter found this bug stuck to the screen on our storm door. He is huge. At least an inch long. My sister in law who lives in the town of West Brighton also found one on her screen door last week. I took pics and posted them to Facebook where some one informed me that this was a grapevine beetle. I have no grapevines in my yard and am not sure if any of my neighbors do but you never know. I've never seen a beetle like this and am wondering if anyone knows if he's been spotted in my area before or is this unusual. I didn't notice any postings from my location. Staten Island does have a large greenbelt area so I'm wondering if he just got lost.
