Caloptilia flavella (Ely, 1915) - No Common Name


No image for this species.
Taxonomy
Superfamily: Gracillarioidea Family: GracillariidaeSubfamily: GracillariinaeTribe: [Gracillariini]P3 Number: 330126.00 MONA Number: 604.00
Comments: Caloptilia is a large genus with nearly 300 described species; 64 species have been described in North America north of Mexico. The larvae begin as leaf-mining sap-feeders, but the latter instars usually exit the mines and feed within a conical roll that begins at the leaf apex or at the tip of a leaf lobe.

Identification
Field Guide Descriptions: Online Photographs: MPG, BugGuide, GBIF, BOLDTechnical Description, Adults: Ely, 1015.                                                                                 
Adult Markings: As described by Ely (1915), the face and labial palps are pale yellowish, while the crown and thorax are straw colored with purplish iridescence. The antennae are yellowish gray and annulated with brown. The forewing has a yellowish tan ground color and is bordered on the costa with bright straw coloration. The costa usually has a series of fine dark dots along the margin, and the cilia on the apex are straw colored and intermixed with tan. The hindwing and cilia are yellow gray. The front and middle legs are dark brown except for the tarsi, which are white with dark brown dots at the joints. The femur of the rear leg is straw colored and shaded with brown near base, while the remainder of the leg is yellow gray.
Wingspan: 10 mm (Ely, 1915)
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larva initially forms a very short, narrow, linear mine that is only a few millimeters long on the underside of a leaf. This then expands into a very small blotch that is about 3-4 mm long and 1.5-2.0 mm wide (Ely, 2015; Eiseman, 2019). The blotches are usually formed near the edge of the leaf, and those observed by Eiseman (2019) became tentiform and full-depth. The larva eventually abandons the blotch and constructs a conical feeding shelter by rolling the tip of the leaf down.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Surprisingly few specimens of this species have been collected or observed since its original description in 1915, and most are from the northeastern US and adjoining areas of southern Canada. These include records from Ontario, Quebec, Nova Scotia, Maine, Vermont, Connecticut, Rhode Island, Pennsylvania and North Carolina (Eiseman, 2019). Tracy Feldman found leaf mines on Morella cerifera in Durham Co. that appear to be those of C. flavella (BugGuide).

Flight Comments: Data on the flight season is very limited. Ely (1915) collected leaf mines in June and the adults emerged a few weeks later in July.
Habitats and Life History
Habitats: Caloptilia flavella is found in association with bayberries and wax-myrtles, which are the host plants. These generally grow in wet to moist coastal habitats such as pocosins, wet savannas, seepage bogs, and brackish marshes. They are sometimes planted as ornamentals as far west as the Piedmont (Weakley, 2015).
Larval Host Plants: This species is a specialist on species of Morella. The known hosts include Pocosin Bayberry (M. caroliniensis) and Common Wax-myrtle (M. cerifera). - View
Observation Methods: Adults occasionally come to lights. Efforts need to be made in North Carolina to search the host plants during June for mines or leaf rolls and rear the adults.
