We began seeing these bugs two evenings ago. They seem to come out at abut 5 in the evening, on our kitchen ceiling. Fly/long hop around. Theyseem to be drawn my the light. They are not as previlent when it gets dark outside.
They are very small about 1/8th inch or smaller. and have the feathered antenna(some of them).
Thanks for your help.

Dear Patricia,
We did open your image yesterday and we did a bit of unsuccessful research, and we decided to postpone posting until we did more research.  We still do not have an identity, so we are posting your request and tagging it unidentified.  Because of its small size and the large numbers of individuals that are appearing in your kitchen, we are presuming this beetle is either a pantry pest or a wood boring species, and we hope that by posting the image, one of our readers will write in with an ID.  Perhaps our new intern Bennett will try to tackle this challenge.  We are speculating that the individuals with the feathered antennae are males.

Update:  Thanks to a comment from Cesar Crash, we are able to update this posting of a Deathwatch Beetle, Ptilinus ruficornis, with a link to our own archives.  According to BugGuide, it feeds on:  “Large, dry portions of dead wood of broad-leaved trees (beech, maple, oak, sycamore…)” and “common pest of woodwork in buildings most frequently encountered wood-feeding anobiid in ne. NA.”

  1. Thank you for your response. The exterminator found them in wood that we had brought in to dry out. The wood was on the fireplace hearth. We thought they might also be cedar beetles.
