Carmenta pyralidiformis (Walker, 1856) (Lepidoptera: Sesiidae) in Louisiana by Vernon Antoine Brou Jr., 74320 Jack Loyd Road, Abita Springs, Louisiana 70420 USA email: [email protected] a b c Fig. 1. C. pyralidiformis phenotypes: a. male, b. female, c. 53 ♂♂ captured adults in pheromone trap. 14 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 7 number of of adults number 0 Fig. 2. Adult C. pyralidiformis captured at sec.24T6SR12E, 4.2 mi NE of Abita Springs, Louisiana. n = 102 I have captured the very small, black in color clearwing moth Carmenta pyralidiformis (Walker) (Fig.1) within Louisiana for over three decades. This species has been captured utilizing ultraviolet light traps and semiochemical lures, in particular commercial lures labeled as Sequoiae Pitch moth, Scentry brand's L103, and Western Poplar. A very efficacious lure involves a combination of varying percentages of Sequoiae Pitch moth lures and Western Poplar lures, e.g. 50/50. Dozens of newly emerged adult males and females were taken by hand using capture jars as the specimens dried their wings while perched upon vertical grass stems along paths where the suspected food plant (False Boneset) Brickellia eupatorioides (L.) Shinners was growing. The newly emerged adult moths appear upon erect, green grass stems sitting within ten inches of ground level during a brief late evening twilight time period in and around 30 Fig. 3. Parish records for minutes before darkness. C. pyralidiformis . At the Abita Springs Study site (Fig. 2), adults were captured from May through October, especially during the month of September. This flight picture is in stark contrast to that occurring at different locations in an adjoining parish as documented by Brou and Lemann (2012). These authors found that False Boneset appeared to be absent at two Orleans parish locations, but adult pyralidiformis was most abundant early in the year March - May at those locations. Apparently, pyralidiformis is using a different host plant at those locations. Eichlin and Duckworth (1988) listed the range of pyralidiformis to include eastern Canada, south to northern Florida, and west to Michigan and eastern Texas. These authors also discuss form "aurantis" (Engelhardt, 1946) in which the typical yellow abdominal band is replaced by orange, this form inhabiting the southern portion of it's range along the Gulf of Mexico and north along the Atlantic coast to South Carolina. Nearly all specimens taken in Louisiana have orange - red bands as illustrated in Fig.1. Occasional specimens are taken in Louisiana having yellow bands along with those having red bands. Eichlin and Duckworth (1988) listed adults appearing late June through September and specific sex attractants E,Z-ODDOH or Z,Z-ODDA. The parish records for pyralidiformis are illustrated in Fig.3.
