Long Horn Beetle

Semanotus australis


A black Long Horn Beetle with an orange-red band across the upper 1/3 of the elytra. It was also covered lightly with long setae. About 1.8 cm long. I put her in a container with a pine twig and two weeks later she had striped off a section of bark with her mandibles and made two holes in the wood - I suppose to place eggs inside. Family Cerambycidae, SubFamily Cerambycinae, Tribe Callidiini, Semanotus australis Giesbert 1993.


I have never seen this species before, she landed on the shirt of the person next to me in a restaurant close to a carpentry shop. They were working with several kinds of wood: including pine, cypress, oak and Huanacaxtle (Enterolobium cyclocarpum). It could have emerged from any of those wood types.


The type and paratypes of this species are from Guatemala (New Progreso) (see reference) and I'm not sure if it has been reported from Mexico yet.
