About Trichius gallicus Dejean, 1821
Trichius gallicus Dejean, 1821 is a beetle species in the subfamily Cetoniinae, family Scarabaeidae. It is very frequently cited in literature under the name "Trichius rosaceus", but this name is permanently unavailable under ICZN Article 11.4, the same as all other names published by Voet. These beetles are found across most of Europe, grow to approximately 10 millimeters in length, and can be seen feeding on flowers from May through July. The sides of the thorax and the dorsal side of the abdomen are covered in fine soft hairs (pubescence), which gives species of the genus Trichius the common name "Bee beetle". The head and pronotum of this species are black, while its elytra are yellowish and marked by several crossing black bands. The first black band typically does not reach the scutellum, all other bands are incomplete, and the second band has a rectangular shape. The pubescence of Trichius gallicus is usually a more orange-red shade than the pubescence of the related species Trichius fasciatus. The median tibiae of this species do not have teeth. In male individuals, only the penultimate abdominal segment bears a band of white hairs.
