Identification

The metallic greenish-golden to reddish-bronze forewing coloration distinguishes this from most other North American Heliozelidae. The purple-tinted hindwing apex is an additional diagnostic feature. Within its California range, it may be separated from other Antispila species by association (Cornus) and the specific mine .

Appearance

Small with wingspan of 7–8 mm. and forewings lustrous with variable coloration: greenish golden to brilliant reddish bronze depending on light direction. Hindwings dark gray, becoming purple toward the apex.

Habitat

Associated with supporting Cornus . Specific habitat requirements beyond presence have not been documented.

Distribution

to California, United States. No documented range expansion or introduced .

Diet

Larvae feed on Cornus (dogwoods). do not feed; mouthparts are reduced or absent as in other Heliozelidae.

Host Associations

  • Cornus - larval Larvae mine leaves of plant

Life Cycle

Larvae are leaf miners, creating brownish blotch mines in Cornus leaves. occurs within the mine; mature larvae cut out an oval shield from the leaf for pupation, a characteristic of the Heliozelidae.

Behavior

Larvae construct blotch mines in leaves of Cornus . At the end of larval development, the larva cuts an oval section from the leaf (termed a 'shield') in which it pupates.

Ecological Role

Human Relevance

No documented economic or horticultural significance. Not known to be .
