Agrilus anxius

University of Alberta E.H. Strickland Entomological Museum

Common NameBronze Birch Borer SeasonalityJune, July and August. IdentificationThis species along with A. liragus are virtually identical in external appearance. The pronotum and top of the head often have brassy to coppery reflections. On beetles of liragus, there may be two pale pub sent spots on the elytra. Characters of the male genital apparatus will separate the species. The easiest diagnostic character if available is host association. These beetles are found on birch.

Agrilus malvastri

University of Alberta E.H. Strickland Entomological Museum

SeasonalityJuly. IdentificationThis species may be recognized by the antennal serrations beginning on segment 5 and the single costa running longitudinally down the centre of each elytron. The specimens from Alberta are lead gray with a slight bronzed cast.

Agrilus liragus

University of Alberta E.H. Strickland Entomological Museum

Common NameBronze Poplar Borer SeasonalityJune, July. IdentificationThe beetle's appearance is very similar to those of A. anxius. Adults have blackish elytra, which tends to have an indistinct coppery reflection and may have a pair of indistinct pubescent spots. The claws are more loosely attached, than in anxius, showing more membrane at their base. The bases of the claws in anxius tend to be swollen compared to liragus. The pygidial spine on female liragus projects strongly and is rather cylindrical. The elytral tips tend to be more strongly serrate and acutely pointed in female liragus than in female anxius. Males may be identified by aedeagal structure. This species may be identified on host plant association, aspen and poplars.

Agrilus politus

University of Alberta E.H. Strickland Entomological Museum

SeasonalityJune, July and August. IdentificationThis 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.

Agrilus crataegi

University of Alberta E.H. Strickland Entomological Museum

SeasonalityJuly. IdentificationIn this species, the beetle's elytra are reddish or have a purple tinge at the apex. The head is green on the front turning coppery brown on the top in the male or entirely coppery in the female.
