Tragocephala jucunda
A lichen-patterned longhorn whose many named colour varieties record just how dramatically one species can rewrite its surface pattern.

Information reviewed15 July 2026
Tragocephala jucunda is a large African and Madagascan longhorn beetle with black, cream and yellow markings. Adults vary considerably in pattern and size, leading earlier taxonomists to name numerous varieties.

What makes this species remarkable?
Taxonomists named at least nine colour and pattern varieties within this species, turning one beetle into a catalogue of forms such as ochreata, luctifera and madagascariensis before modern catalogues reunited them.
Its pale bands are broken into irregular islands across black armour, making a beetle up to 38 millimetres long resemble patches of lichen and light on bark rather than one continuous animal.
The species occurs on both Madagascar and the African mainland, a distribution that spans the Mozambique Channel and raises the question of ancient separation versus rare long-distance dispersal.
