Chlorostrymon simaethis, the silver-banded hairstreak, is a North and South American butterfly in the family Lycaenidae.

Females are grayish brown, sometimes having iridescent purple on the basal area of the wings.

The silver band on the hindwing juts out towards the margin and turns back in, forming a V shape.

Beyond this band, there is a dark brownish-red patch with a variable amount of silvery-white frosting.

[6] The silver-banded hairstreak is found in habitats such as subtropical woodlands, deserts, and hammock edges.

These butterflies are usually a very pretty light green with a white streak along the top of the wing.

[7] The female lays her eggs singly on the young fruits of the host plant.

[9] There is a dark greenish middorsal stripe edged on each side with red ovals.
