Negro bugs.

Old comments below reflect an early assumption that these might be shining mold beetles:

There were several of these beetles on the closed blooms of this plant. These plants were in an open meadow maybe 100 ft. from a creek.

The beetles were roughly lady beetle sized, approx. 6mm in length.

The Peterson Beetle Guide (1) says shining mold beetles are "common on flowers or foliage." It also mentions the antennae are oval 3-segmented clubs. I'm not sure if the antennae of these beetles matches that or not. You can see the antennae of the center beetle, but I'm not sure what the correct term for that type of antennae is.

The Peterson guide also states that the larvae live in the heads of flowers, so peharps that has something to do with the strange reddish bumps on the plant.

Shield Bugs?
Hey Mike,

These may be shield bugs...See how there is no split down the middle of their back (where a beetle's elytra would open so it could fly). Also note the fella on the right, looks like there is a beak sucking on the bud...There are some other pics of them on the site here (1)

Negro Bugs?
Hi Tony, I think you might be right...I never thought about the elytra not being split on the back. I looked up shield bugs in my Peterson Insect Guide (1) and the image and description for the Negro Bugs (Corimelaenidae) looks about right. "Broadly oval, convex, shining black." It mentions they are common on flowers, and the antennae in the drawing are similar to my photo.

This Insects of Cedar Creek Image looks similar.

I agree
Look like negro bugs to me. I wonder when the racial thing will be changed:-) Shoot, humans will be "Hetero sapiens" in no time. Ha!

Looks good...
Hey Mike,

That looks pretty good to me, if someone else can confirm, I'll make a guide page for it.

More Info
Here's another page I found on this type of bug:

The second photo, top bug, looks quite similar, and the text description seems to fit.
