Usually I don't collect beetles but I've got some and I would need someone to help me identify them. First two from left are collected in July in Alberta-Canada, Rocky Mountains, Kananaskis, 51°01'58"N 115°00'48"W , 1400m third : Toronto-Canada also in July.

Any ideas, anyone about those beetles?

Maybe all the Coleopterists are on 'holiday' right now, out catching beetles in strange places.

PaulK, you have 2 families of beetles present. Going from left to right the first 2 are long horned beetles (Cerambycidae). The third on the right is a flat bark beetle (Cucujidae). The Cucujidae are a small family of beetles represented by 4 genera / 59 species. Your specimen is most likely the "Red flat bark beetle" (Cucujus clavipes); which is probably the most commonly encountered species of this type of beetle throughout North America. Of the 1st Cerambycid on the far left; it is a commonly known as a "Sawyer beetle"-- subfamily Lamiinae. The Lamiinae or (flat faced longhorns) are one of the 2 largest subfamilies in the Cerambycidae. There are now some 750 genera attributed to just the Lamiinae. I will go only so far as to say that your sawyer beetle likely belongs to the genus: Monochamus. The specimen in the middle is as mentioned also a Cerambycid; belonging to the Lepturinae (lepturine beetles). The vast number of lepturinae are day-light loving / flower pollinating longhorn beetles. These longhorns are always very slender in appearance superficially with a thorax that is narrower than the wings --- which tend to be pointed. Their legs are usually long and un-gainly looking in appearance and they are very active, fast moving beetles. There are about 150 genera attributed to the Lepturinae. Hope this helps you somewhat....

Thank you Trehopr1, indeed your information is useful to learn more about Coleoptera. Knowing what families and genus I will be searching more to see if I could find what species are they.

I ma not specialist of the region but the Parandrini is a male Neandra (maybe brunnea)

Thanks to forum's team help I (hopefully right) get to identify those beetles: 1 (left): Monochamus scutellatus-male 2 (middle): Anastrangalia sanguinea-male 3 (right): Neandra brunnea-male Please correct if this is wrong.

It appears that I stand corrected on my initial identification of the beetle on the far right. Admittedly, I too would never have imagined that beetle was a Cerambycid. This tribe the Parandrini is certainly one to fool even a seasoned collector such as myself. I really should have noticed that the wing covers are convex in appearance as opposed to being flat in Cucujids. If you were to look up the Cucujidae and specifically C. clavipes you would see just how similar superficially it is to N. brunnea. I think even the antennae of both look similar. However, the Cucujidae are in fact seldom encountered by collectors generally and their capture is more a matter of sheer luck. One would almost have to regularly tear into rotting logs or dying trees with loose bark to ever find such niche beetles. Kudo's go out to Ciervo and Africaone for their sharp eye and familiarity with the Parandrini ! I do try my very best to be helpful with the knowledge I have attained over the years and if anything I remain generally reserved about going too far with identification of any kind --- unless there is absolute certainty in my mind.
