This plant first caught my eye because the leaves stand out as oddly shaped among the rest of the vegetation. Then I paused to photograph one in bloom and found this awesome red bug.

It's a Cotton stainer nymph (Dysdercus suturellus.)

I don't have too much else to say about this plant. It grows close to home, but not in my yard, so I'm not sure if butterflies use it or not; I just haven't watched it enough.
