The subfamilyTheclinae is a group of butterflies, often referred to as hairstreaks, with some species instead known as elfins or by other names. The group is part of the family Lycaenidae, the "gossamer-winged butterflies". There are many tropical species as well as a number found in the Americas. Tropical hairstreaks often have iridescent blue coloration above, caused by reflected light from the structure of the wing scales rather than by pigment. Hairstreaks from North America are commonly brown above. Few Theclinae are migratory. Members of this group are described as 'thecline'.
Systematics
The systematics and phylogeny of the numerous Theclinae has not reached a robust consensus yet. The arrangement presented here is based on Savela (2007), but be aware that it is probably oversplit and several tribes may not be valid. Nonetheless, the tribes as listed here generally seem to represent monophyletic lineages, but whether this is indeed so and whether these are distinct enough to warrant this level of separation remains to be resolved.
The former tribe Aphnaeini has now been given subfamily status (see Aphnaeinae).[1]
