Like other Strymon species, it is expected to exhibit hilltopping behavior where males perch on elevated terrain to seek mates.
Gray Hairstreak
Strymon melinus, the Gray Hairstreak, is a small lycaenid butterfly widespread across North America. Males exhibit density-dependent mating tactics, defending perches on hilltops at low densities and switching to patrolling behavior when intruder numbers increase. The species thrives in weedy, disturbed habitats and urban environments, with a notably long flight season from February to November at low elevations. It is considered stable or increasing in parts of its range, including California's Central Valley.
Red-crescent Scrub-Hairstreak, Red-crescent Hairstreak
Strymon rufofusca is a small butterfly in the family Lycaenidae, commonly known as the Red-crescent Scrub-Hairstreak or Red-crescent Hairstreak. It is found in North America, though specific details about its biology and ecology remain limited in available sources. The species is part of the hairstreak group, characterized by thin tail-like projections on the hindwings. Its MONA (Hodges) number is 4338.
Yojoa Scrub-Hairstreak
Strymon yojoa is a small hairstreak butterfly in the family Lycaenidae, commonly known as the Yojoa Scrub-Hairstreak. It is native to North America and belongs to a genus of butterflies often associated with scrubland and open habitats. The species was originally described as Thecla yojoa by Reakirt in 1867 and later transferred to the genus Strymon. Like other hairstreaks, it likely exhibits the characteristic tail-like hindwing projections and rapid, erratic flight patterns typical of the group.

Systasea is a genus of skipper butterflies in the family Hesperiidae, established by Edwards in 1877 as a replacement for the preoccupied name Lintneria. The genus comprises three recognized species distributed in the southwestern United States and Mexico. Members are commonly known as Powdered-Skippers and are characterized by distinctive wing morphology including transparent spots on the forewing and deeply notched hindwing margins.
Arizona Powdered-Skipper
Systasea zampa, known as the Arizona Powdered-Skipper, is a spread-wing skipper butterfly in the family Hesperiidae. It occurs in the southwestern United States and Mexico, with records from Arizona and adjacent regions. The species is considered uncommon to rare in many parts of its range, with adults active in early spring. It is one of three species in the genus Systasea, all characterized by distinctive wing morphology.
Telegonus is a genus of skipper butterflies (family Hesperiidae, subfamily Pyrginae) established by Hübner in 1819. The genus is currently treated as a synonym of Astraptes. Species historically placed in Telegonus are distributed in the Neotropical region.

The genus Urbanus comprises long-tailed skippers found primarily in the Americas, though specific traits for U. rickardi have not been independently documented.
West Coast Lady
The West Coast Lady is one of three North American "painted lady" butterflies, endemic to western North America. Long-term monitoring by UC Davis researcher Art Shapiro since 1972 documents this species as in conspicuous decline across its California range, with populations dwindling even in urban and weedy habitats where it was once abundant. The species is known to overwinter as adults in mild climates, emerging on warm winter days to nectar.

Vanessa virginiensis, commonly known as the American Lady or American Painted Lady, is a widespread butterfly found throughout North America. It belongs to the brush-footed butterfly family Nymphalidae and is closely related to the Painted Lady (Vanessa cardui) and the Red Admiral (Vanessa atalanta). The species is known for its distinctive wing patterns and its habit of feeding on flower nectar. Unlike some of its Vanessa relatives, the American Lady is not strongly migratory in the mass-movement sense, though it does expand its range seasonally.
