are about 30 Callophrys species, the
most widespread of which is the Green Hairstreak
rubi, which is distributed across most
of Europe and temperate Asia. There are 9 other species found in
temperate Asia, and one restricted to Spain and North Africa. In
North America there are a further 25 species, of which 7 are found
in Mexico. Only 2 species are found further south, one of which is
endemic to Guatemala.
The upperside wings
of all Callophrys species are dull
earthy brown in both sexes although several including
estella, dospassosi and
guatemalena have a blue iridescence.
The undersides of some species are marbled in shades of brown and/or
greyish-brown, but the majority of species are iridescent green.
Most species are marked with a white 'hair streak' line across both
wings, but this is highly variable within a given species, and may
be broken into a series of dashes or dots, or entirely absent.
Almost all species have a slight lobe at the anal angle of the
hindwings, and a few species possess short filamentous tails.
