Explanation of Names
FLAVOCOSTELLA: from the Latin "flavus" (yellow) + "costa" (a rib); [the costa of an insect is the anterior marginal rib of its wing]; refers to the yellowish strip along the costa of the forewing.
Size
Wingspan 15-18 mm.
Identification
Adult - forewing purplish-black with cream-colored strip along costa stopping short of apex; a spur of the strip points inward in the PM area, like a sharp-pointed tooth that touches (or nearly touches) the corresponding "tooth" on the other forewing. Hindwing gray.
Range
Quebec and Maine to Florida, west to Texas, north to Manitoba. (2), (3)
Season
Adults fly from May to August (June and July in the north).
Food
Larvae are leaf rollers and tiers on aster, goldenrod, sunflower. (4)
Life Cycle
Larval leaf roll; larva; pupa; adult
See Also
At least two other Dichomeris species are similar (aleatrix and inserrata) but the yellowish "tooth" in their PM area is truncated and blunt, and does not come close to touching the corresponding "tooth" on the other forewing.
