Graphosoma semipunctatum is a species of true bug living exclusively in the Mediterranean region. It is very close to Graphosoma lineatum. It can be distinguished from G. lineatum by black dots along the pronotum instead of lines.They are found abundantly on plants in the family Apiaceae, especially eryngium species. Its red color serves to warn its predators that it is not palatable.

Congratulations Kostas, your striking Red Half-spotted Stink Bug has been voted Spotting of the Week!
"Found exclusively in the Mediterranean region, this Red Half-spotted Stink Bug (Graphosoma semipunctatum) is our Spotting of the Week! This shield bug in the family Pentatomidae resembles the more familiar Italian striped bug or minstrel bug (Graphosoma lineatum), but with a striking difference: black dots along the pronotum instead of lines. Their aposematic markings serve to deter predators".

Your spotting has been nominated for the Spotting of the Week. The winner will be chosen by the Project Noah Rangers based on a combination of factors including: uniqueness of the shot, status of the organism (for example, rare or endangered), quality of the information provided in the habitat and description sections. There is a subjective element, of course; the spotting with the highest number of Ranger votes is chosen. Congratulations on being nominated!
Thank you both Felipe and Felix.
Beautiful shots!
