The remarks on an Arizon species of Labena grallator said, "Townes described this color variant as the subspecies ochreata. Four subspecies were recognized, grallator in most of the North American range and westward to Colorado, balteata in southern Texas, xutha in Colorado and New Mexico, ochreata in Arizona, and lutea on the California border of Arizona."
This specimen was found (twice) at Santa Ana NWR in March 2011. The thoracic stripes, dual colored ovipositor, yellow outline of face, all seemed to match. The only non-match was the striped abdomen. So, I thought, perhaps, this might be the southern Texas variant. If not, I'm happy to frass it. With ovipositor, the wasp was at least 2 inches long.
