Dendroctonus brevicomis

University of Alberta E.H. Strickland Entomological Museum

Common NameWestern Pine Beetle SeasonalityFlight period is from early May through June. This may be extended if conditions remain warm. IdentificationDeclivity is moderately steep, pubescent and has weak, granulate punctures on the interstriae. Depressions are found on the declivity between the first and third striae. The frons has a median groove that extends from the epistomal process to the upper level of the eyes. Usually very dark brown and between 2.0 and 4.7 mm. Closest ally is D. frontalis Zimmermann.

Dendroctonus murrayanae

University of Alberta E.H. Strickland Entomological Museum

Common NameLodgepole Pine Beetle SeasonalityFlight period is from late June through to early September. IdentificationThe frons has fine punctures with sparse granules. The pronotum has coarse punctures. Has a narrow epistomal process. The declivity is steep and convex. The striae on the declivity are weak impressions and have minute punctures on the declivity. This species has distinct male genitalia. Size ranges from 5.0 mm to 7.3 mm. Pronotum is dark brown and elytra are reddish brown. The distinct punctures on the frons and pronotum allow it to be distinguished from D. punctatus. The distinct frons, male genitalia and galleries distinguish it from D. rufipennis.

Dendroctonus ponderosae

University of Alberta E.H. Strickland Entomological Museum

Common NameMountain Pine Beetle SeasonalityFlight period begins in mid July and lasts until late August. This may vary with local climates. IdentificationThere is no frontal groove on the frons. The pronotum has coarse, closely spaced punctures that may have granules. The elytral declivity is dull and may have small granules. It may look similar to D. jeffreyi Hopkins, but pronotal features and smaller size distinguish it. It may also look similar to D. adjunctus Blandford.

Dendroctonus pseudotsugae

University of Alberta E.H. Strickland Entomological Museum

Common NameDouglas Fir Beetle SeasonalityFlight period is from early April to early September. IdentificationThe frons is distinct with fine punctures and granules. The pronotum is finely punctured. The declivity has punctures on the interstriae. The above characters as well as the distribution allow D. pseudotsugae/i> to be distinguished from D. simplex/i>.

Dendroctonus punctatus

University of Alberta E.H. Strickland Entomological Museum

Common NameAllegheny Spruce Beetle or Boreal Spruce Beetle SeasonalityExact information of flight period is not known. IdentificationD. punctatus has a uniform brown color. It has a smooth frons with deep punctures and no granules. Large punctures are found in the declivity. These features distinguish it from D. rufipennis and D. murrayanae, its closest North American relatives. This species is almost identical to D. micans, its European counterpart.

Dendroctonus rufipennis

University of Alberta E.H. Strickland Entomological Museum

Common NameSpruce Beetle SeasonalityAdults flight period is from late May through July. IdentificationThe frons of this species has coarse punctures and close granules. Its male genitalia, galleries and host allow it to be distinguished from its closest ally, D. murrayanae.

Dendroctonus simplex

University of Alberta E.H. Strickland Entomological Museum

Common NameLarch Beetle SeasonalityFlight period is from early May through to late August. IdentificationThis species has a coarsely punctured but smooth frons, as well as a coarsely punctured pronotum and declivity. It can be distinguished from its closest ally, D. pseudotsugae, by its distribution and smaller size in sympatric regions.

Dendroctonus valens

University of Alberta E.H. Strickland Entomological Museum

Common NameRed Turpentine Beetle SeasonalityFlight period is from May to October. In warmer climates adults may fly all year. IdentificationThis species has a reddish brown color, small punctures on the lateral parts of the pronotum, as well as small granules on the declivity. It can be distinguished from D. terebrans by its distribution as well as these characters.

Scolytus multistriatus

University of Alberta E.H. Strickland Entomological Museum

Common NameSmaller european elm bark beetle. SeasonalityOverwintering generations will emerge as adults in June or July, while their progeny will emerge either in August and September, or overwinter. Some of the adults that emerge in August and September may breed and giving rise to another generation of overwintering larval individuals (Bright 1976). IdentificationAdults can be about 2.2 - 3.0mm long and are reddish brown in colour. Both males and females will have a cylindrical and narrow spine arising from the anterior edge of the 2rd abdominal sternite (Bright 1976, LaBonte et. al. 2003). Teeth are usually present on the posterior-lateral margins of the 2nd to 4th abdominal sternites (LaBonte et. al. 2003).

Scolytus muticus

University of Alberta E.H. Strickland Entomological Museum

Scolytus piceae

University of Alberta E.H. Strickland Entomological Museum

Common NameSpruce engraver. SeasonalityAdults have been collected in Alberta from May to August. IdentificationAdults may be 2.4 to 3.3 mm long and are shiny black in colour. The frons is flattened and depressed in between the eyes (Bright 1976). The second sternite is not concaved and rises vertically to meet the elytra. In both males and females, there is a median spine arising in the center of the 2nd abdominal sternite (i.e. base of spine does not touch the anterior or posterior margin of 2nd sternite) (Bright 1976).
