Host unknown
First US record coll'ed in 1925 in Brownsville, TX (Chemsak & Noguera 1998).
A second specimen labeled as being from Texas was seen during the preparation of this report (USNM collection). It is labeled "Port la Vaca, at Brownsville, II-7-1968, J. B. Kee." Since there is no such location as "Port la Vaca at Brownsville," but there is a Port Lavaca, Texas (Calhoun County), one can speculate that this specimen was perhaps intercepted in commerce and not collected in the field. This view is supported by the fact that the USNM Collection includes a great amount of insect material that was submitted by inspectors to the United States Department of Agriculture taxonomic service unit for identification. It seems highly unlikely that this specimen originated in Port Lavaca, Texas and was later intercepted at Brownsville. (1)
Texas considers this sp. a SGCN (3)
