Trichodes alvearius is a species of soldier or checkered beetle belonging to the family Cleridae, subfamily Clerinae.

The elongated elytra show a bright red colour with black bands.

These beetles are widely distributed across southern Europe in Albania, Czech Republic, Italy, Greece, France, Germany,[1] Hungary, Poland, Spain, Switzerland, the western half of the Balkans, and in North Africa.

The adults can be encountered from May through August on the flowers, mainly Apiaceae, Asteraceae and Crataegus species, feeding on pollen.

However, they integrate their diet with small insects that they actively hunt, especially Oedemera, Psilothrix, Stenopterus and Clytus species.
