leaf beetle

6193 We have had a number of these in our basement lately (April 2018, North Vancouver, B.C.) primarily, but not always, in the bathroom. They are about 4-5 mm in length with black backs/wings with a distinct brown patch towards the head. I’m not sure if they can fly… they sometimes seem to jump. Thank you for any assistance you can provide!

Number 6193 – This looks like a leaf beetle (Coleoptera: Chrysomelidae); if they can jump, they may be flea beetles (tribe Alticini in said family). to the best of my knowledge, none of these are household pests, yours likely are simply accidental intruders.
