The species of Graphosoma all look fairly similar:
Graphosoma italicum has large black and bright red bands, the legs are black, except maybe for the third tibia.
Graphosoma lineatum is quite similar to G. italicum, but always has pale reddish legs and a paler orange ground colour.
Graphosoma semipunctatum has orange legs and the red and black bands on the pronotum are interrupted into black dots.
Graphosoma melanoxanthum has dark connexivi with small red points. It is distributed in South Russia, Turkey and Iran
Graphosoma creticum has thin black bands on pronotum, a smaller body, and more orange in colour. It is present in Crete
Habitat
