I think this long-horned beetle looks great. It is Hippopsis lemniscata. It feeds on common ragweed (Ambrosia artemisiifolia), which as far as I am concerned, makes it even better but unfortunately the "destruction by larval H. lemniscata does not appear to affect the competitive or reproductive capacities of A. artemisiifolia."
