Monarch Danaus plexippus	Upperside of male is bright orange with wide black borders and black veins; hindwing has a patch of scent scales. Upperside of female is orange-brown with wide black borders and blurred black veins. Both sexes have white spots on borders and apex. The Viceroy butterfly (Limenitis archippus) is a Mullerian mimic; it has similar coloration and is also distasteful.
Chalcedon Checkerspot Euphydryas chalcedona	Extremely variable. Forewing narrow. Upperside is black to dark orange-brown with yellow, red, and sometimes white spots. Underside with yellow and orange-red bands.
California Sister Adelpha californica	This is a medium to large sized brown-black colored butterfly with a relatively narrow dorsal forewing postdiscal creamy white colored band above with a relatively large orange patch on the forewing. Superficially similar looking above to Lorquin's Admiral (<em>Limenitis lorquini</em>) but can be readily separated by the lower placement of the orange forewing patch and the blue lines on the ventral surface of the wings. Can be difficult to separate from Bredow's Sister (<em>Adelpha bredowii</em>) which does not occur in the U.S. and the Arizona Sister (<em>Adelpha eulalia</em>) which does occur in the U.S. Ranges of <em>californica</em> and <em>eulalia</em> are not known to overlap in the USA. Generally, this species is smaller than <em>eulalia</em>. It is less violet below. The dark and bluish ventral hindwing postdiscal bands are poorly developed, sinuous. There are two basal orange bars on the HW below while <em>eulalia</em> has only one. The blue bar along outer edge of white HW bar is incomplete while <
Painted Lady Vanessa cardui	Upperside is orange-brown with darker wing bases; forewing with black apex patch and white bar on leading edge; hindwing submarginal row of 5 small black spots sometimes has blue scales. Underside has a black, brown, and gray pattern with 4 small submarginal eyespots.
Gray Hairstreak Strymon melinus	One tail on hindwing. Upperside blue-gray with large red spot near tail. Underside of spring/fall form is dark gray, summer form is paler gray. Relatively straight postmedian line is white, bordered with orange on the inside edge.
Lorquin's Admiral Limenitis lorquini	Upperside is black with white median bands on both wings; tip of forewing is orange-brown. Underside is reddish-brown with white markings.
Fiery Skipper Hylephila phyleus	Antennae are very short. Male wide black stigma. Underside of the hindwing is scattered with small black spots. Female: Upperside is dark brown with a very irregular orange band. Underside of hindwing is pale brown with paler checks.
Mylitta Crescent Phyciodes mylitta	Upperside is bright reddish orange with narrow dark markings. Lacks the prominent black inner marginal spot of Phyciodes pallidus. Underside is yellow-orange with somewhat blurry rusty orange markings.
