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.

    Hey Daniel, is this beetle maybe mis-categorized under “resin bee”?

      Wow, I don’t know how that happened, but with over 18,000 postings, there are probably other miscategorizations. It is now corrected.

    I have one of these beautiful beetles in my collection. Its a Four-spotted sap beetle, Glischrochilus quadrisidnatus. I think it’s a species from the Handsome Fungus Beetle family.
