Assassin bug

6403  What kind of insect that I discovered this morning hidden under plate. Is it a cockroach or? Thank you. Montreal, Qc. Canada

 

Number 6403. This is an assassin bug (Hemiptera/Heteroptera: Reduviidae) called the masked hunter (Reduvius personatus), an introduced species with a cosmopolitan distribution. These are general predators on other small arthropods, and are reputed to have a very painful (but not dangerous) bite.
