Phyllobius argentatus Linnaeus, 1758
Common names: Phyllobe argenté [Fr]
Tubize, BRABANT ● Belgium
Description: A slender and elongate species, parallel sided and brilliant metallic green. The size is 3.8-6 mm.
The upper surface has scales almost round to slightly elongate and with pale pubescence. The head is elongate with large and prominent eyes, the temples parallel, only a little wider than rostrum. The upper surface is wekly convex, the pubescence almost recumbent.
The rostrum is quadrate, with strobes appear transverse behind antennal insertions otherwise filled with scales so indistinct.
The antennae are long and narrow, testaceous.
The scape is much longer than width of head, curved at base and evenly thickened to apex. The second segment of funiculus is longer than first, the segment four twice as long as broad and the club narrow and pointed.
The pronotum is transverse, convex with sides evenly rounded at middle, constricted towards base and apex, with the surface coarsely and densely punctate, usually invisible beneath dense scaling, pubescence curved and slightly erect.
The scutellum is distinct, densely scaled. The elytra are elongate (2:1) and convex, surface uneven; raised at humerous and behind scutellum, transversely depressed behind these raised areas then evenly convex to apex. The scales are usually dense so that striate are barely visible, the scales recumbent, the pubescence semi-erect and long, as long as width of interstices on disc.
The legs are testaceous, as antennae. All femora are strongly toothed and with metallic scales. The tibiae aresometimes darkened towards apex.
Biology: This essentially arboreal species occurs on a variety of broadleaved trees. Early in their season the diurnally active adults are probably easiest recorded from Crataegus, a little later they are common on Quercus (Oak) and Betula (Birch) but also occur on Fagus (Beech) and Corylus (Hazel). They are also recorded from Populus, Salix and Alnus (Morris).
