This butterfly is considered uncommon in south Texas and is a rare stray to Arizona.
This butterfly is very small - somewhat the size of the Pygmy-Blue. The butterflies perch and sway from side to side - we call it the Cyna wave. The underside (ventral view) is a pale gray to light blue and dotted with many small spots and dashes. The topside (dorsal view) is blue with a brownish coloring towards the outer margins of the wings. They use Snake Herb (Acanthaceae Dyschoriste linearis) as a larval host in south Texas. During late Summer through the Fall seasons several females can be seen flitting around and ovipositing in a patch of Snake Herb growing at our local NABA park.
They might also use Wood Sorrel (Oxalis spp.) as a larval host plant.
