The red "spot"

Is not always there, but it's a clincher when it is.
As they age, the flower heads also tend to become concave rather than convex - not as reliable, but it helps with the "gone over" ones.

In the top right hand corner ...

... you can see a couple of inflorescences (I can't tell whether they're opening or going over) with the characteristic bracts of Daucus carota.

Yarrow is one of the two species (the other is valerian) commonly confused with umbellifers - I still occasionally confuse them at first glance, but on a closer look the inflorescence (capitulescence in the case of yarrow) is quite different). Yarrow is a radiate composite - that is its flowers are florets compressed into tight clusters (capitula) with both ray (ligulate) and disc (tubular) florets. The capitula are disposed in a dense corymbose capitulescence, giving a general appearance similar to the compound umbel of most umbellifers.
