Superfamily: Pyraloidea Family: CrambidaeSubfamily: MusotiminaeP3 Number: 80a1264 MONA Number: 4740.00
Identification
Field Guide Descriptions: Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Dyars (1906)                                                                                 
Adult Markings: Undulambia striatalis is a boldly marked species that is unmistakable (Dyars, 1906). The ground color of both the forewing and hindwing is shining white and boldly marked with a series of longitudinal brown or ocherous streaks that extend from the middle of the wing to the outer margin. The basal half of the forewing has a brown base that is followed by a white band with varying amounts of ocherous shading on the costal half. The white band is followed by a brown, wavy band that is darkest on the dorsal half and adjoins the streaked distal half of the wing. A subapical white line is present at around four-fifths that extends roughly perpendicular from the costa to about one-fourth the wing depth. The basal half of the hindwing has similar markings to the forewing, with a brown base that is followed by a white band, then a darker brown band that adjoins the streaked distal half of the wing.
Wingspan: 18-20 mm (Dyars, 1906)
Adult Structural Features: The forewing is subfalcate at the apex with a crenulate margin, while the hindwing is sharply crenulate.
Immatures and Development: The larval life history of this species is undocumented.

Flight Comments: The adults have been found from February through July in different areas of the range. As of 2023, our two records are from late May and early June.
Habitats and Life History
Habitats: Our two records as of 2023 are from a pine savanna and a sandy spoils area on a barrier island.
Larval Host Plants: The host plants are undocumented. - View
Observation Methods: The adults are attracted to lights, but very few specimens have been found throughout the range. It is uncertain if this reflects true rarity or the fact that the adults are only weakly attracted to lights.
