Mellissius eudoxus Wollaston

Eudoxus Scarab Beetle (Mellissius eudoxus)

This species was endemic to the island of Saint Helena, where it apparently was very common in former times; its larvae were called hog-worms and were thought to cause great damage to the grasslands by feeding on the roots of the grasses.:

Indeed we met with the eudoxus almost universally throughout the rather elevated central and south-western parts of the island (particularly in the vicinity of Cason’s, High Peak, and West Lodge), and more sparingly even in the northern ones, whereas of the adumbrates I did not procure so much as a single example during our six months’ sojourn in the island; so that, if the “hog-worms” do really “play so important a part in the destruction of the grass on the high lands, by feeding on its roots, that large patches, and sometimes whole fields, are laid bare,” I suspect that it must be the M. eudoxus, and not the comparatively rare adumbrates, which is mainly responsible for the damage.” [1]


The Eudoxus Scarab Beetle was apparently not found during the most recent field searches and appears to be possibly extinct.


The depiction below shows another species of that genus, the Shaded Scarab Beetle (Mellissius adumbrates Wollaston), which apparently still survives on the island.
