Idaea scintillularia (Hulst, 1888) - Diminutive Wave Moth


Taxonomy
Family: Geometridae Subfamily: Sterrhinae Tribe: Sterrhini P3 Number: 910511.00 MONA Number: 7105.00                                                                                  
Comments: One of thirty species in this genus that occur in North America north of Mexico (Pohl et al., 2016). Thirteen have been recorded in North Carolina.
Identification
Field Guide Descriptions: Online Photographs: MPG, BugGuide, BOLDTechnical Description, Adults: Hulst (1888)                                                                                  
Adult Markings: One of our smallest Geometrids and very strikingly marked in gray, yellow, and rufous. The large patch of dove gray covering the basal half of the forewing and a similar patch of mixed gray and rufous at the base of the hindwing contrast strongly with the bands of yellow and reddish-brown that cover the outer parts of the wings. The discal spots are black and conspicuous in some individuals.
Wingspan: 10 mm (Hulst, 1888)
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Distribution in North Carolina
Distribution: Our records come mainly from the Piedmont, with one record from a brownwater floodplain along the Roanoke

Flight Comments: Adults fly during the summer, from mid-June to early September
Habitats and Life History
Habitats: All of our records come from riparian forests or shoreline habitats along brownwater rivers or Piedmont streams
Larval Host Plants: Apparently unrecorded
Observation Methods: Our records were all obtained from blacklight sampling
Status in North Carolina
Natural Heritage Program Status: W3
Natural Heritage Program Ranks: GNR SU
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: We have only a small number of records for this species. It appears to be at least somewhat specialized in terms of its habitats, which have generally not been heavily sampled. More surveys conducted along Piedmont rivers and floodplains may show that it is more common than it now seems. Identification of its host plants may also help clarify its conservation status in North Carolina.
