Hololepta (Leionota) reichii Marseul is a widespread but rarely encountered natural enemy of social bees, so we evaluated feeding habits and behavior of such a clown beetle regarding bees, beehive by-products, and other sources of food under a monitored environment. The experiments revealed that H. reichii preferentially predates larvae and pupae of social bees extracted from brood cells, but also feeds on dead adult stingless bees and on larvae and pupae inside cells. This note reports the first finding of clown beetles (Coleoptera, Histeridae) in a hive aggregation of stingless and honey bees in natural conditions and expands the known distribution of the species to the state of Espírito Santo, the second record in the Brazilian Atlantic Forest.

Hololepta ( Leionota ) reichii Marseul 是群居蜜蜂的一种普遍但很少遇到的天敌，因此我们在受监控的环境下评估了这种小丑甲虫在蜜蜂、蜂箱副产品和其他食物来源方面的摄食习惯和行为。实验表明，灵芝优先捕食从育雏细胞中提取的群居蜜蜂的幼虫和蛹，但也以死亡的成年无刺蜜蜂和细胞内的幼虫和蛹为食。本说明报告了在自然条件下在无刺蜜蜂和蜜蜂的蜂巢聚集中首次发现小丑甲虫（鞘翅目，海星科），并将该物种的已知分布扩展到圣埃斯皮里图州，这是巴西大西洋森林的第二项记录。
