Fungus Feeder - Piesocorynus plagifer - male

Fungus Feeder - Piesocorynus plagifer - Male
Lexington, Fayette County, Kentucky, USA
June 4, 2004
A fungus weevil. This long horned male was first seen in late May 2004, soon to be joined by a short horned version, and both of them munched on this black patch of fungus on the bark of a Maple tree for several weeks before disappearing. The guide page used to suggest that only the larva ate fungus but the current version seems to not rule out the adults doing so. For the first time in six years a similar patch of fungus has appeared on the same Maple and I hope to learn who may be coming to dinner.

the fungus
Nice photo. The black fungus dinner in this photo belongs to the fungal family Xylariaceae. I add this because, my dear bug people, we have very little info on which bugs eat which fungi, and we dearly wish we knew more.

Beetles do like fungus...
Nice to know that we have a mycologist on board! The same sort of fungus on the same tree in 2010 was completely undermined by the tunnels of grubs of a much smaller beetle. I didn't expect this and never saw a live adult emerge. The truth was discovered only after the thin surface crumbled showing the tunneling.

thanks a lot, Kathie
i couldn't agree more: insect host relationships with fungi are appallingly inadequately understood; hope you add host info to other BG pix of fungivorous beetles as well

Piesocorynus plagifer Jordan, i believe
the link was send to Dr Valentine right away, but no answer yet [he's usually very quick to respond]

Moved from Fungus Weevils.

Moved from ID Request.

what a treat, Roy -- lovely beast
i'll ask Dr Valentine -- do you have any other shots, like a head closeup? kept the beetle?

Other photo's
I have a number of additional photo attempts but with the digital cameras of the day, not to mention my lack of macro experience and the deep shade of this patch of fungus this photo provides the most detail while also showing the snacked upon fungus. The best "eye" photos are of the short horned version which would require an other ID request. I will attempt to find at least one other picture which doesn't embarrass me too much which might help with an ID.

feel free to show me the embarrassing ones offline
i'll swear to confidentiality
