Phyllopertha horticola, or the Garden Chafer, is a beetle from the Scarabaeidae family. It is approximately 10mm in size with chestnut brown wing casings which are covered in tiny hairs. The head legs and thorax are dark green in colour. Like other chafers there are fan-like flaps at the ends of their antennae. A broadly elongate species with near-parallel elytra, dark forebody and appendages, which are usually to some extent metallic, and pale brown elytra. Dorsal surface finely punctured and with sparse but distinct pale pubescence. Antennae black or with the basal segment brown; the club consists of 3 lamellate plates in both sexes. The Garden Chafer, Phyllopertha horticola (L.), has three larval instars, the third ending in hibernation, which gives way to a prepupal stage. The development cycle occupies 12 months and only one generation is present in the soil at any time. From a study extending over five years, 1948 to 1952, the cycle from egg to adult in the English Lake District may be outlined as follows:— Der Gartenlaubkäfer (Phyllopertha horticola) ist ein Käfer aus der Familie der Blatthornkäfer (Scarabaeidae). Gelegentlich wird er auch irreführend „Junikäfer" genannt. Allerdings werden vor allem der Gerippte Brachkäfer (Amphimallon solstitiale), aber auch andere Vertreter der Gattungen Amphimallon und Rhizotrogus (wie zum Beispiel Rhizotrogus marginipes) so bezeichnet. The Garden Chafer, Phyllopertha horticola (L.) is the chief British representative of a type of world-wide pest. The following summary concerns the adult and its reproduction under laboratory conditions. Adult feeding affects neither the number of eggs produced by the ovaries (productivity) nor the number laid (fecundity).
