Species Euxoa tristicula - Hodges#10723

10723

3.5-4.0 cm wingspan

Head and body grey, with a contrasting black thoracic collar. The forewings are light grey, with the costa even paler, especially near the base. The normal lines are obsolete or nearly so, indicated by a few dark scales at best. There is a prominent black basal streak, and the area proximal to the orbicular and between the orbicular and the reniform is filled with black scales. The subterminal line is faintly marked with dark scales, especially near the costa. The fringe is grey. The hindwings are dirty white, with the veins lightly marked with darker scales. The fringe is white. Form nesilens lacks the prominent black markings on the forewings and the thoracic collar. The relatively large size, pale grey color and sharp black markings will separate most tristicula from other Euxoa sp. Euxoa tristicula belongs to the subgenus Pleonectopoda, characterized by the prominent twist or subbasal coil in the vesica of the male. This description from E.H. Strickland Entomological Museum
