Theclini

Theclini is a tribe of small butterflies in the family Lycaenidae, within the subfamily Theclinae. Members of this group are commonly referred to as Theclininae or hairstreaks, and many species display the characteristic tails on the hindwings and fine, linear wing patterns that aid camouflage among twigs and bark. Wing coloration varies across genera, ranging from browns and grays to iridescent blues and greens.

Taxonomically, Theclini has seen revisions as researchers refine the boundaries among tribes within Lycaenidae. The tribe is anchored by the type genus Thecla, and its circumscription has shifted with advances in molecular phylogenetics. Consequently, the exact composition of Theclini can differ among classifications, with some genera moved to closely related groups in different systems.

Geographically, Theclini species are found worldwide, with particular diversity in temperate and tropical regions. They inhabit a range of environments, including woodland edges, meadows, scrub, and forest interiors. The life histories of Theclini members are diverse but share common features typical of Lycaenidae: larvae feed on a variety of host plants, and many species exhibit interactions with ants (myrmecophily) at one or more life stages. Adults primarily feed on nectar and pollen from flowers.

Conservation status within Theclini is heterogeneous; while many species are locally common, habitat loss, climate change, and fragmentation threaten certain populations. Ongoing taxonomic and ecological research continues to clarify relationships within the group and inform conservation priorities.
