Economic Importance:

Limited.

Known host plants: 

Dictyssa fenestrata - Simmondsia chinensis (Link) C.K. Schneid. (jojoba, Simmondsiaceae)

Dictyssa leonilae  - Juniperus californica Carrière (California juniper, Cupressaceae)

Dictyssa marginepuncatata - Simmondsia chinensis (Link) C.K. Schneid.

Dictyssa obliqua - Ambrosia chenopodiifolia (Benth.) Payne (San Diego bur ragweed, Asteraceae)

Dictyssa schuhi - Purshia tridentata (Pursh) DC. (antelope bitterbrush, Rosaceae), Ceanothus velutinus Douglas ex Hook. (snowbrush ceanothus, Rhamnaceae)

Dictyssa transversa - Artemesia sp. (sagebrush, Asteraceae), Sideroxylon sp. (Sapotaceae), Zea mays L. (corn, maize; Poaceae)

Hosts from Wilson et al. (1994); plant names from USDA PLANTS or Tropicos.

Recognition:

Dictyssa can be recognized among the Gaetuliini by the forewings covering the abdomen (vs. Danepteryx, Dyctidea, or Osbornia); forewing nearly as wide as long and semicircular in shape, costal margin decidedly rounding; forewing partly opaque, usually with an oblique hyaline band across clavus and corium; veins of corium forming small irregular cells (vs. few large cells in Dictyonia), some of which usually (not always) are vitreous or light colored.

A key to species is given in Doering 1936.

Collecting

Dictyssa is collected by inspecting likely host plants or sweeping.

Molecular resources: As of this writing, data for Dictyssa so is available on Genbank; but no data is available on Barcode of life.
