Information reviewed15 July 2026
Frea sparsa is a Madagascan lamiine longhorn whose identification depends on the exact placement of pubescence, punctures and a transverse elytral band. It is a compact example of camouflage built from texture.

What makes this species remarkable?
The beetle’s apparent “bark” is assembled from thousands of short hairs laid in contrasting directions; a pale transverse band interrupts the wing cases and breaks the outline into separate visual fragments.
Breuning separated Frea sparsa from close relatives using the density and spacing of cuticular punctures together with the exact shape of that median band — microscopic patterning functioning as a species fingerprint.
The species is confined to Madagascar, where the Crossotini longhorns diversified into numerous locally endemic forms; losing this single island population would erase the entire known species.
