Does that beetle looks like this beetle mentioned in this thread?:

My bad!, a correction. Beetle is here:

There is no picture in the link.

Sorry, It's there in my second post. When I hit the GW link, I can see it now. Perhaps your firewall is blocking the pic?

I didnÂt think I had a firewall. But I found the picture by googling the caption. IÂve wondered for a while what they look like: always good to be forewarned.

No picture in mine, either. No space for a picture. No message that a picture was blocked.

In response to the OP - no lily beetles are not as big as lobsters! You can see the size in the link. And they live on the plants not in the soil. No idea what you have found. Can you post a photo?

Here is a link that might be useful:
