Genus Okanagana
Synonyms and other taxonomic changes
Okanagana Distant, 1905
Explanation of Names
Likely named for the Okanagan region/river (or Native American people) of British Columbia.
Numbers
56 Recognized species north of Mexico and one in Baja (aurantiaca).
Size
~20-30mm, a few are a bit smaller. Wing span: ~50-75mm
Identification
Superficially similar to Clidophleps, Neoplatypedia, and Playpedia.

Separated from Platypedia and Neoplatypedia by the position of the costal node at 1/2 the length of the wing, and from Clidophleps by the trapezoidal shape of the radial cell. Can't really be confused with Okanagodes except for O. pallidula, which is not sympatric.

The identification of Okanagana is difficult. In terms of images, the ideal combination for a male is a dorsal and ventral shot, an exposed wing, and dorsal and lateral views of the exposed uncus (hidden normally by the valve). For females: dorsal and ventral shots with a closeup of the female genital plates.

Note: colors bordering tergal bands are notoriously variable and are a rough character to use. Females also tend to have a broader head, which can obscure the shape of the apical pronotal angle.
Range
Okanagana are most speciose in California, but range into the midwest, across Canada, and Okanagana viridis is an allopatric species in the deciduous southeast. One species is found in Baja: O. aurantiaca, but hasn't been recorded in recent history.
Habitat
Highly varied. Some are host plant specific (O. nigriviridis, O. opacipennis, O. rubrovenosa, etc.), others are highly habitat specific (O. villosa, O. pallidula).
Season
Generally mid June to mid July and into August. Can be found as early as April and as late as September in some years.
Life Cycle
Remarks
Often a song is vital to an ID, and sometimes it takes hours to figure out an ID from a specimen. There are certain Okanagana that are fairly easy to identify from photos, many other should be taken as a provisional ID. Other species just have to be left alone.

O. magnifica, cruentifera, mariposa, and venusta follow a variation on a protoperiodical lifecycle. Their emergence schedule is governed by a cumulative rainfall threshold, emerging only when it has been reached. Other Okanagana follow a typical protoperiodical cycle (2-5 years with variably-sized emergences) that are independent of rainfall.

Details of songs are slowly being added as they are published. Currently, Chatfield-Taylor and Cole 2019 has the song metrics for 23 taxa and they're being incorporated into the guide.
