Almost all neotropical and North American Theclinae species are
placed in the Eumaeini.
The tribe is not especially well represented in collections, so for
a long time many remained unstudied and were inappropriately filed
away in the 'convenience' genus Thecla.
Many taxonomists have attempted to rationalise the systematics of
the Eumaeini, the most recent being Robbins who published a revision
in 2004, reclassifying the taxa into 83 genera. Currently there are
1058 known species. Taking into account their small size, secretive
behaviour, and the great similarities between many species, it is
estimated that about another 200 species probably remain to be
Ministrymon comprises of 23 known
species, variously distributed from s.w. USA to Peru and Argentina.
Males are dark brown on the upper surface of the wings, with a
metallic blue sheen on the hindwings and around the basal area of
the forewings. The ventral surfaced in most species is grey, with a
broken staggered red streak on both wings. With the exceptions of
cleon and azia
all Ministrymon species also have
additional black and/or red spots in the basal area of the
hindwings, and a dark bar at the end of the discal cell of the
is distributed from s.w. USA to central Mexico.
This species is found in rocky river valleys, gorges and canyons in
otherwise hot dry landscapes. It occurs at elevations between about
The eggs are laid
on the foodplant Prosopis ( Fabaceae).
The fully grown larva has a series of raised whitish humps arranged
in 2 rows along its back, and a bristly lappet protruding below the
spiracle on each segment. It is green, with a broken white lateral
line. The bristly pupa is chestnut brown mottled with blackish. It
is formed on the upper surface of a leaf, attached by the cremaster
and a silk girdle.
