What's That Bug? does not endorse extermination

A few weeks ago I noticed many insects that look very similar to fireflies. The body is black and head has red/orange markings. They seemed to appear all on the same day and now we have hundreds around the house. We have never noticed them (at least in this quantity) before. Any idea?

Black Firefly

Dear Bugged Out,
We are trying to answer some older mail we didn’t open in the past month.  This is a species of Soldier Beetle, Rhaxonycha carolinus.  BugGuide has some additional information on the species.

I don’t know, this looks more like Lucidota atra, a diurnal species with reduced light organs, but a true firefly.  Have a look: http://bugguide.net/node/view/5361

    this is a completely black bug, the shape of a firefly (long oval). i’m not sure it has antenna as bold as the picture above. when I scooted it off my washcloth, it jumped instead of flying. I’ve seen these bugs many times but just curious what they were because I saw something about fireflies on tv that said not all fireflies light up. what do you think?

    I found in my home an all black bug that looks like a fire fly, but it is all black, no other coloring. It was walking across my rug.

    THe weather has been hot and humid and little rain
