Catocala micronympha Guenee in Louisiana by Vernon Antoine Brou Jr., 74320 Jack Loyd Road, Abita Springs, Louisiana 70420 email: vabrou@bellsouth.net The Quercus feeding medium-sized noctuid species Catocala micronympha Guenee is quite common where found in Louisiana. This species has more than a half dozen different appearing forms distinguished by highly variable forewing maculation and color, a few examples of which are shown in (Fig 1). At some locations, micronympha populations do not exhibit many of the different appearing forms found at other locations e.g. variations illustrated in fig. 1a,e were not captured at St John the Baptist parish in 12 years of continual light trapping despite an abundant population there. C. micronympha has one brood peaking late May (Fig. 2). Fig 3 illustrates parish records by this author. C. micronympha was first reported in Louisiana by von Reizenstein (1863) and again by Chapin and Callahan (1967).C. micronympha is reported from Ontario to Florida and Minnesota to Texas Heppner (2003). b a c d e Fig. 1.
