Hi bugman,
I was taking a walk yesterday in San Marcos, CA (just north of San Diego) and found an odd bug. It looked like two bugs stuck together at their bums. Their bums were red (can’t really tell by the photo…sorry). I thought it might have been just two bugs stuck together but a few paces down the road I saw 2 more like this. It looks like one of the bodies is bigger and it moves in the forward direction that the bigger bodied bug would move. Hope this is enough helpful info to figure out what this is. Thanks!!

  1. Hello,
    What an incredible site. I am in San Diego, and saw this unusual bug crawling in my driveway.
    And yes, it looked like to bugs stuck together at the rear. I did a quick search on the net, and it popped right up with a picture of the insect. (red Shoulder bug)
    Thank you,

  2. Just found a pair in Boscawen, New Hampshire. Made my day! Sad to say…more action than I’ve seen in a long time!!!
