|scientific name Agrilus politus |
June, July and August.
This is a very broad ranging and variable species. It is likely to contain several cryptic species. The pygidium lacks a projecting ridge, the elytral colour tends towards green, coppery or leaden. This species is similar to A. burkei and A. pseudocoryli. There is great difficulty separating A. burkei, from politus. At one time, burkei was a subspecies of politus. In Alberta there are blue "politus" mixed in with the usual coppery ones. Either the blue ones are confused burkei or there is really no difference and they are all one species, politus.
Reared from willow and maple (Bright, 1987). In Alberta the beetles have been collected on alder, aspen, birch, spruce, lodgepole pine, balsam poplar and willow. All Alberta rearing records are from willow.
North America (Bright, 1987).
