I have found these in my basement over the last 6 months both in early fall and winter. I am in Southern Ontario, Canada. It is small white and looks like a crab. When I have see them, I only see one.
This is an immature Assassin Bug, and it is commonly called a Masked Hunter, Reduvius personatus , because the sticky surface of the immature insect causes dust and debris to stick to it, masking it in its surroundings. Masked Hunters might bite if carelessly handled, but they are important predators. If allowed to remain in the home, they will naturally help to control populations of undesirable creatures like Cockroaches and Bed Bugs.
