Filatima xanthuris (Meyrick, 1927) - No Common Name


No image for this species.
Taxonomy
Family: GelechiidaeP3 Number: 421134.00 MONA Number: 2181.00
Comments: The genus Filatima contains around 80 species that are primarily Holarctic in distribution, with the greatest diversity in semiarid areas of the western United States and Mexico. Their larvae are leaf tiers that feed primarily on legumes, but also exploit a variety of other vascular plants.
Identification
Field Guide Descriptions: Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIFTechnical Description, Adults: Hodges and Adamski (1997)                                                                                 
Adult Markings: The following description is based on that of Hodges and Adamski (1997). The head, labial palp, thorax, and tegula are grayish-brown to dark brown, while the antenna is dark brown above and yellowish gray underneath. The labial palp is recurved to near the vertex, and the third segment is nearly as long as the second segment. The second segment has a conspicuous furrowed brush. The forewing is dark brown distally, with the anterior margin of the wing dark brown basally. The margin becomes mottled dark brown and gray to three-fourths the length, then pale grayish brown to the tip. A dark-brown subcircular spot is present at three-fifths the length of the cell, and another one at the end of the cell. The discal spots are variable and can be large or small, equal in size or with the distal spot larger, and separated or united. The mid-discal spot is absent in some specimens. The upper surface of the hindwing is pale grayish brown, and darkens slightly towards the apex. The undersurface of the male has curtain scaling. Most of the abdominal segments are grayish brown above with a distal white margin. The legs are mostly dark brown with pale grayish brown intermixed. The tibia has a narrow white band at one-half the length and at the apex, while the apex of each tarsomere is white. Filatima xanthuris is difficult to distinguish from F. ornatifimbriella based on external traits and is best distinguished by using genitalia (Hodges and Adamski, 1997).
Forewing Length: 6.0-10.1 mm (Hodges and Adamski, 1997)
Adult Structural Features: Hodges and Adamski (1997) have descriptions and illustrations of the male genitalia, which are distinctive.
Adult ID Requirements: Identifiable only by close inspection of structural features or by DNA analysis.
Immatures and Development: The larval life history is undocumented.
Distribution in North Carolina
Distribution: Filatima xanthuris has been found at scattered locations through North America. Hodges and Adamski (1997) documented specimens from the mountains of North and South Carolina, as well as in Arkansas, Oklahoma, Colorado, west Texas, New Mexico, Arizona, Utah, Nevada, Washington, and Oregon. It also occurs in Manitoba, Saskatchewan, Alberta and British Columbia.

Flight Comments: The adults have been collected from 26 March to 10 October (Hodges and Adamski, 1997).
Habitats and Life History
Habitats: The preferred habitats are undocumented.
Larval Host Plants: The larvae appear to feed on legumes. The known genera that are apparent hosts based on rearing records include Thermopsis, Lupinus, Robinia, and Vicia (Hodges and Adamski, 1997).
Observation Methods: The adults are attracted to lights.
