Saw this bug on a window in my house. Never saw a bug with antennae like this!

Edit: I live in NY, and saw this bug about 1 PM. Also, I found there were several more on other windows and I think I might have a problem!

    $\begingroup$ I am not a good naturalist but I would say some kind of Scarabaeidae $\endgroup$

  • $\begingroup$ In case anyone finds it relevant: many of these bugs (10-20 it seems) were brought in from outside, nearby the house, with the firewood. Apparently these bugs are drawn to wood. $\endgroup$

Sure looks like a Deathwatch Beetle (Ptilinus ruficornis) with pectinate antenae.

This Encyclopedia of Life site also has some more information.

    $\begingroup$ The antennae are also a sign of the animal's sex: both figures (Q & A) are males (the antennae of a female would be sawtoothed). $\endgroup$
