Bugguide contributing editor Richard Lareau collected male and female of this species and others in a large, very tough, malodorous, irregular-shaped pollypore fruiting body clinging to a downed swamp tupelo tree in a tupelo and cypress swamp. See images of two of his finds here
(Edit: The above links go to blank pages because Lareau, in a dispute with a newly added Bug Guide editor who frassed some of his images, opted to remove all his images from the site. My series of images will serve as proxy for Lareau's first post of this as-yet undescribed species.)
Richard sent me some good-sized pieces of this fungus so I could get some live images of its beetle population. My early efforts were very frustrating and I was beginning to think Richard had played an early April Fool's joke on me when suddendly I saw ciid tunnels after one manly rip of the tough fungus, and there in the big plastic bowl over which I was working lay this male of the same apparent species.
Because this may represent an undescribed species I have not held myself to a paltry few images. Further, in view of the limits of my lens system, I have invited Tom Murray to try out his superior equipment on this little guy, so bugguide will be awash in images of this ciid species.
This specimen and any others I might find in Richard's fungus will be sent to Glenda Orledge, a Ciidae expert in England. She is already familiar with bugguide and with Richard's find and quite anxious to examine any specimens (hint, hint, Richard).
