I found this beautiful beetle walking over a fungus, near Medellin, Colombia, at about 1700 m over the sea level. So I think it could be a “pleasing fungus beetle”, but I only find references of this species in Central American countries.
During my search in internet, I also found the latin word “gibbosus” that means “humpback”. It seems to be clearly the case of this beetle.

Dear luchogu,
Your images of a Pleasing Fungus Beetle on its namesake food are spectacular, but they took us so long to format for the web that we don’t have the after final energy to research their identity, but we believe the genus
Gibbifer is correct.
It’s a new day and we are linking to a Costa Rican Pleasing Fungus Beetle submission from earlier in the year that might be
Gibbifer gibbosus, but we were never able to substantiate that identification.  Insetologia from Brazil has an image of a Pleasing Fungus Beetle that look identical to your individual that is identified as being in the genus Cypherotylus, a name we cited as obsolete in a posting from our archivesFlickR includes an image of a Pleasing Fungus Beetle in the genus Gibbifer, but it looks nothing like your individual.  A search for Gibbifer led us to another FlickR image from Peru that looks similar to your individual, but it is only identified to the genus level.

I found this distinctive black beetle while I was out last night moth hunting, and since he seems to be missing from your archives I’m passing him along! This particular species of polypore fungus beetle is about 1-1.4 cm long (according to Bugguide; consistent with my specimen). That little orange scutellum (right between the thorax and the abdomen) is the key to identifying it, along with the overall rounded shape. Evidently they like living in dry fungus and decomposing trees, both of which we have in abundance around here, though this one was drawn to a lamppost.

Dear Helen,
Thank you for your continued efforts to supplement our archives with your excellent images.  BugGuide does have some additional information on this Fungus Beetle that does not have a common name.

I found this beetle while hiking in the Rincon de la Vieja National Park in Costa Rica. I’m guessing that it belongs to the genus Gibbifer based on the ID that I found here on your pages. But I couldn’t find any matches for a species ID. Maybe you or some of your readers can help.

Pleasing Fungus Beetle

Hi Siggy,
You are correct that we have several examples from Costa Rica of Pleasing Fungus Beetles in the genus
Gibbifer, but we cannot substantiate their species identity.  There is a posting on Project Noah that is identified as Gibbifer costaricensis.  That same species is represented on Biologia Centrali Americana, however, the obsolete genus name Cypherotylus is used.  It is also important to understand that insects do not respect international boundaries drawn up by humans.

Daniel,
Thanks for replying so quickly. I seen that plate from Biologia Centrali Americana as well and thought insect #3 matched mine pretty closely. But when I did a search on Gibbifer gibbosus, what I assume would be the current name, I found pictures of beetles without the black band across the middle. I don’t know how much variability can be expected in a species, but maybe it’s just a variant.
I have a few more pictures of some insects that I want to ID from that hike. If I can’t come up with anything myself I may resort to enlisting your help again. Even if I can ID them, I’ll submit the images for use on your site.
Siggy

Hi again Siggy,
We would love to see any identified images from your hike.  It is much easier for us to post interesting images of interesting creatures without having to do any additional research.  Please include the species name and location in the subject line to catch our attention as traffic is once again increasing due to warming weather in much of the northern hemisphere.

Hi,
Was out walking and thought these bugs were beautiful and have no idea what they are or what they are doing. Are they attacking a tree or feasting on a fungus? Would love help getting them identified. I’ve only seen them once in the forest.
Thanks you!

Dear Nature Lover,
These are Pleasing Fungus Beetles in the genus
Megalodacne.  They are feeding on fungus as their name implies.

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!!!!!

Pleasing Fungus Beetle

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.

Handsome Fungus Beetle

Dear Shirlynn,
This beetle is very distinctive looking, but we haven’t the time to research it right now as we are preparing to leave the office to spend Thanksgiving with family for several days.  Perhaps in our absence, one of our readers will digest turkey at the computer and they might write in with a comment that identifies the species.

Handsome Fungus Beetle

Hi Daniel and shirlynn:
This is a Handsome Fungus Beetle (Endomychidae), not to confused with the Pleasing Fungus Beetles (Erotylidae). Both are large families of beetles that specialize by feeding on fungi or rotting wood. Your beetle is in the genus Eumorphus, but it gets a little tricky after that as there are many to choose from and they are all quite similar. As far as I can determine, at least seven species are native to Singapore and there are probably more. Eumorphus marginatus looks like a pretty close match but I really can’t be certain that that is it. Regards. Karl

Thanks so much for the assistance Karl.  We will need to create a new subcategory for this Handsome Fungus Beetle.
