Containing group: Greya

Adult Characteristics

Wing expanse 13-17 mm. Body pale ochreous to near white. Forewings with a white base color, and with spots of dark or light brown; sexes are strongly dimorphic, with males having isolated darker patches on a solid background, whereas females have more extensive dark on the forewings, creating fused spots and a checkerspot pattern. Hindwings uniformly gray.

Comparison with Similar Species

The species superficially resembles G. reticulata and some forms of G. variabilis. It can be distinguished from both by the blunt, short-spined pollex in the male and the presence of large signa in the female.

Host, Oviposition, and Larval Feeding Habits

Unknown, but females often found resting on or near Osmorhiza chilensis (Apiaceae) and Tiarella trifoliata (Saxifragaceae).

Geographic Distribution

Known from southern British Columbia and Alberta in Canada, and from Washington, Idaho, and Montana, USA.

Habitat

In moist coniferous forest from sea level to 1500 m. It often coexists with G. variabilis and G. mitellae.

Typial habitat on Olympic peninsula, Washington, USA.

Ecological Notes

Even though this species visits Lithophragma flowers just like G. politella, and drink nectar from the flowers, there is no indication that they contribute to pollination (Pellmyr et al 1996).

Type

Holotype in the Academy of Natural Sciences, Philadelphia, USA.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
