Hello. My friend found this bug in his horse pen in Wimberly Texas on Sept 18, 2013, probably in the morning about 10 or so. We would just please like to know what it is…anything you can suggest would be helpful and appreciated. 🙂

At first we couldn’t locate this Longhorned Borer Beetle in the family Cerambycidae when we searched BugGuide, so we did a web search with some key words and we found a matching image on the Texas Beetle Information site that calls this the Red Headed Beauty, Stenaspis verticalis insignis (Casey), and includes a map with county sightings as well as this taxonomy: “Family Cerambycidae, Subfamily Cerambycinae, Tribe Trachyderini.” With that information, we headed back to BugGuide where we also found the Red Headed Beauty pictured with this information: “Adults strongly attracted to plant exudates. Larval host unknown, probably utilizes a living host, possibly mesquite or acacia (Dan Heffern, pers. comm.).” BugGuide also provides this information: “On October 14, 2005, 2 miles west of Utopia, Uvalde Co., Texas, Mitch Heindel found 5 pairs incopula and a few unattached males on Evergreen Sumac (Rhus virens) Anacardiaceae, and a couple of singles on another of the same shrub. Hovore et al. (1987) report aggregations of of this sp., including many mating pairs, on stems of Baccharis in San Patricia Co., TX in October. See also Goldsmith (1989).” The species is reported from Arizona and Texas as well as Mexico. The Arizona subspecies lacks the red head. This is a new species for our site and though the image shows the remarkably striking coloration of the Red Headed Beauty, we wish the photo was more in focus.
