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?

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
