The North American subspecies is Horama panthalon texana.
Phylogenetic Sequence # 930465
Lafontaine & Schmidt (2010) listed two species of the genus Horama in America north of Mexico. (1)
The wingspan is 32-34 mm.
Abdomen purplish/brown/black with many orange rings, hind legs black and orange with a large feathering on the tibiae (males (2)*), antennae black with orange tips, thorax and head black with orange and white markings, wings brown.
Some examples lack the orange abdominal bands (3)
Thought to be a Batesian mimic of paper wasps, Polistes species (4).
*Sexual dimorphism in tibial scales not mentioned by Dietz and Duckworth (5), and they say males and females are similar.
c. TX to S. Amer., strays from AZ to FL - Map (MPG)
Usually found on flowers, esp. Eupatorium (3)
Moth Photographers Group - large map with some distribution data. (6)
Adults nectar.
Life Cycle
Caterpillar and larval food unrecorded (almost). "Adult has been collected at Wislizenia refracta var. mamillata (Capparidaceae)" (5). That plant is called " jackass-clover or spectacle fruit". One record of caterpillar on Desert Yaupon, Schaefferia cuneifolia, (Celastraceae)--see iNaturalist.
Common to abundant in southmost Texas (3).
Verification needed that only males have tufts of hair-like scales on tibiae--all images to date seem to have this feature, and some of these have more plumose antennae than others, indicating both sexes are being seen--Patrick Coin 4 February 2021.

Subspecies: (7)
Horama panthalon panthalon (Panama, north Colombia, north Venezuela and the Antilles)
