Spider beetles

6663.    Hi, Please help me identify these bugs, I keep finding them in the nooks and crannies of my old house. They are always in groups of many and they keep crawling. I have never seen them before in my life. Thank you. Karim. Montreal, Quebec. Canada


Number 6663.  These are spider beetles (Coleoptera: Anobiidae; subfamily Ptininae) in the genus Mezium, likely M. affine, known as the shiny or northern spider beetle. These can be pantry pests, infesting a wide variety of dry stored food products. Click here for more detailed information.
