Dear bugman, I found these cool black & orange bugs this week out back on a fungus. They were 1/2 – 3/4 inches long. The color caught our eye immediately. what is this bug? Also, if you look closely at the picture you can also see small larva / baby bugs in the background. Are the big bugs feasting on the small ones? Could this fungus be their nest? Thanks!!!!!

Dear Liz,
This beauty is a Pleasing Fungus Beetle in the family Erotylidae and the genus
Megalodacne.  We cannot ascertain if it is Megalodacne heros, which is larger, or Megalodacne fasciata.  According to BugGuide:  “Larvae feed on bracket fungi. Adults overwinter under bark, often in groups.”  The larvae are grubs, and we believe that may be a larva visible in the photo you supplied.
