Fungus Beetles
You guys have a great site! I found a dead tree while hiking near Colorado Springs today that had 50-100 of these beetles on it. Many of them were copulating (sorry I didn’t get pics for your insect sex page). I’ve seen them before and wondered what they were. After looking through 6 pages of beetle pics I finally found it. Thanks so much! Further research seems to say that the scientific name has changed to Gibbifer californicus, but it is definitely the right beetle. I’m attaching a picture even though the one you have is probably better.

Hi Heidi,
Thank you for taking the time to forward your photo of a Pleasing Fungus Beetle. We think is is quite good.

Bug question for the Bugman
Hello Bugman,
What an amazing and beautiful website! I wish I stumbled across it sooner. It is a great inspiration; it makes me want to learn more about these awesome creatures. Thank you. We found this beetle crawling on a rock near a mountain stream in Colorado. It was sometime around October, 2005. Any ideas? I tried looking it up but had no luck.

Hi Alicia
We decided to check in on Eric Eaton for help and he quickly responded: ” It’s a pleasing fungus beetle, Gibbifer californicus, in the family Erotylidae. This is one of the larger, more spectacular species, found in the southwest U.S.” The adults and larvae both feed on a variety of wood rotting fungi, hence the name Pleasing Fungus Beetle. Additional research turned up this amusing name: Humpty Dumpty Erotylidae.

Variety of burying beetle or…..?
I think it’s great that there are so many people out there who are
interested enough in bugs to find out what they are. And I think it’s even better that there is a site where people can go to get help from well-educated and dedicated people such as you. Thanks! Now, on to my bug. I found these in a rotten area of a maple tree in my yard here in northeast Ohio. Looking through your site, I saw many pictures of burying beetles which look quite similar. But these little guys seem to have larger red bands and the head and thorax do not seem so prominent. Any ideas?

Hi Steven,
This is a new genus for our site. This is a Pleasing Fungus Beetle in the genus Megalodacne. They are often found in colonies in rotten wood and beneath loose bark. There are two possible species, M. fasciata which grows 9-15 mm and M. heros which is considerably larger, ranging 18-21 mm.
