Cottonwood Longhorn (Plectrodera scalator)

Recommended Posts

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 -

Wow, that is an awesome bycid! Finding something like that in your own front yard is even more amazing! It's rare that I get anything at my house that's interesting. Maybe one day I will live in a location that has lots of cool bugs.

The iridescent species Plinthocoelium suaveolens is also found here at my place, and appears either blue or green, depending on viewing angle.  Its host tree is Bumelia (Sideroxylon lanuginosum) -
