Appearance
Trichius gallicus is present in most of Europe, they are about 10 millimeters long and can be encountered from May through July feeding on flowers.The first black band usually does not reaches the scutellum, other bands are incomplete and the second has a rectangular form. The color of hair usually is more orange-red compared to ''Trichius fasciatus''. Median tibiae are without teeth. In male only the penultimate abdominal segment has a band of white hairs.
Naming
In older literature Trichius gallicus frequently appears under the name "Trichius rosaceus", but this name is permanently unavailable under ICZN Article 11.4, as are all of Voet's names.Later the beetle has been referred to as "Trichius zonatus" by many, many authors and can still be found under that name in recent literature and databases, but Krell (2012) argued that the correct name for this species should be Trichius gallicus and Löbl & Löbl (2016) followed suit in their second edition of the Palearctic catalogue, specifying these subspecies:
⤷ ''Trichius gallicus gallicus'' Dejean, 1821 for the pan European beetle
⤷ ''Trichius gallicus zonatus'' Germar, 1831 for a closely related beetle from Sardinia and North Africa
