Beetle Trapping

This week we've been trapping pine beetles for a colleague in Louisiana. From what I understand, he is trying to determine whether the western pine beetle (Dendroctonus brevicomis) in southern Utah is, perhaps, its own sub-species. For that, he needs up to 50 beetles. I went out to an area where I knew there were multiple active Dendroctonus populations and hung the traps. So far, we've collected at least 60 or 80 beetles. Unfortunately, as you can see from the picture, many of them are roundheaded pine beetles (Dendroctonus adjunctus). I don't know if we're going to get 50 westerns.
