Species of beetle
Nemognatha chrysomeloides is a species of oil beetle (Meloidae) endemic to Central and South America.
Ecology
Nemognatha chrysomeloides is a parasite of Melitoma marginella and M. segmentaria from Mexico to Argentina. Both N. chrysomeloides and Melitoma are restricted to the same host plant – Ipomoea – and so the rate of parasitism may be comparatively high.[1]
Taxonomy
Nemognatha chrysomeloides was first described by Carl Linnaeus in his 1763 work Centuria Insectorum, under the name Meloe chrysomeloides. It is a very variable species, and as such, many synonyms have since been published:[2]
