Ground beetle

6854.          Just found one bug in my bathroom. I don’t know its type. Your help is appreciated. Waterloo, Ontario. Canada

Number 6854. This appears to be a ground beetle (Coleoptera: Carabidae) in the subfamily Lebiinae, Click here for more detailed information. There also some beetles in the family Anthicidae (ant-like flower beetles) having a similar appearance, but their antennae usually are slightly clubbed rather than thread-like in carabids. Strictly an accidental and harmless intruder.
