In this article, we will learn about the magnificent thick-legged flower beetle. The thick-legged flower beetle (scientific name Oedemera nobilis) is a common beetle found in Western lowland Europe and the Mediterranean. This beetle is also known as swollen thighed beetle or false oil beetle. These beetles are named so due to the swollen hind legs and femora of the male beetles. Females, in contrast, have thin femora. The flower beetle, Oedemera nobilis is bright metallic green in color beetle and has hard-shelled elytra. Their Elytra (hind wings) of this species of beetle has a separation and does not cover their underwings completely. These small insects feed on the pollen and the nectar of open flowers like the Asteraceae, Rosaceae, Apiaceae, and Cyperaceae. They love the warm weather and the sun so they can easily be spotted hovering around flower heads in the summer season especially during the months of May to August.
