North American texts list approximately two hundred flower longhorn beetle species.
The large number translates into many species lacking common names. The color differences between the male and female Dimorphic Flower Longhorns explain the common name.
A western species, males have black bodies, females have red wing covers with black spots.
Flower longhorns, genus Evodinus, inhabit areas of New England, the Northeast and Pacific Northwest. Evodinus monticola vancouveri is the Pacific Northwest subspecies.
The Leptura genus is one of approximately fifty different Flower Longhorn genera.
Leptura obliterata, picture three is a western species.
The Canadian Flower Longhorn (Stictoleptura canadensis) sports a bi-color (red and black) elytra along with a bi-color set of antennae.
A few different subspecies inhabit forested areas of the United States, all probably naturalized citizens.
The amount of black and red coloration can change between subspecies, and the Arizona subspecies has red elytra.
Another western species, Xestoleptura crassipes can be identified by the yellow legs with a black and yellow wing pattern. Two yellow spots sit at the bottom of the wings.
