Mealworm beetle -
Tribolium madens
Edmonton, Alberta, Canada
May 18, 2008
Size: About 4-5mm
This invaded my bag of chocolates (never leave a bag open...). It was much smaller than any species I know.
It was Cadbury's chocolate buttons, so the European import species below sounds likely.

Large Trilobium
According to http://www.grainscanada.gc.ca/storage-entrepose/sip-irs/bfb-tm-eng.htm T. madens is "large for flour beetles, 3.9 to 5.1 mm long".
I found this beetle inside Cadbury's chocolate buttons which was probably a European import item.
Going by the fact that my beetle was definitely at least 4mm, what other species stand in the way confusion wise?

Any ideas?
I see T. madens would still be a new "guide species"...what species could it be confused with?
