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 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 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 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 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 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 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.

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.

Trypodendron lineatum

University of Alberta E.H. Strickland Entomological Museum

Common NameStriped Ambrosia Beetle SeasonalityAdults' flight period is between spring and late summer. IdentificationAdults are recognized by their smooth shiny elytral surface, the interspaces usually very minutely and irregularly punctured and raised subapical margin of elytra that gives them a broadly rounded appearance when viewed from above. Elytra are usually bicoloured with alternating patterns of five dark and four pale stripes. General appearance of adults colour is very dark brown to black. Females and males differ in size and sculpture. Length is 3mm – 3.5mm in females and 2.7mm – 3.2mm in males. Frons of females is convex with surface reticulated with sparse granules while in males they are concave with lateral margins ornamented by abundant hair. Anterior margin of pronotum is usually unarmed (without teeth) in both sexes but rounded in females and straight in males (Bright, 1976; Wood, 1982).

Trypodendron retusum

University of Alberta E.H. Strickland Entomological Museum

SeasonalityInitial flight in spring (early April) till early May, then June to late summer. IdentificationAdults are distinguished by their large size, smooth and shining surface of elytra with apical margin appearing subacuminate when viewed from above. Colour is uniformly black when mature but young adults have a pale yellowish brown colouration at the base of the pronotum to the apex of elytra. Length is 3.8 – 4.6 mm for females and 3.6 – 4.3 mm for males. Frons are convex with surface reticulated with sparse granules in females. In males they are concave with lateral margins ornamented by abundant hair. In females the anterior margin of pronotum is usually rounded, armed with four teeth, the median pair being larger while in males the margin is feebly recurved and unarmed (without teeth) (Bright, 1976; Wood, 1982).

Trypodendron rufitarsis

University of Alberta E.H. Strickland Entomological Museum

SeasonalityNot investigated, but probably similar to T. lineatum (Bright, 1976). IdentificationRecognized by their dull finely reticulated surface of the elytra, with apical margin appearing subacuminate, narrowly rounded posterior margin, when viewed from above. (Bright, 1976; Wood, 1982). Frons of male deeply concave with lateral margins ornamented by abundant hair and anterior margin of pronotum straight and unarmed. Females frons are convex, surface reticulate with fine, sparse granules. Anterior margin of pronotum is rounded and unarmed. (Bright, 1976; Wood, 1982)
