This does not appear to be a pest as I can determine no direct damage but they flock to my outdoor plants. I use reem oil for pest control and it seems to work well. This critter is usually on the stems or stalk, not the leaves. Over the last two seasons this has been the only insect of note at the two different locations about 100 yards apart. Comments appreciated about any potential harm. This bug is about 1/2 inch long, blue body color with an orange head.
