Found this big female Cottonwood Longhorn (Plectrodera scalator) on a cottonwood in my front yard over the weekend. I've not seen one of these for at least several years. Very unique looking, large species - probably my favorite native US cerambycid. The pattern on the elytra is unique to each individual. The life cycle takes between 1-3 years -
