Centennial Woods Natural Area, Burlington, Chittenden County, Vermont, USA
April 21, 2008
After much digging and watching, I determined that these tiny beetles were responsible for the burrows that I found riddling the mud along Centennial Brook.

They're all Heterocerus
I really need to publish my thesis!

yes you do
to bring us --and them mudlovers-- back to sanity

Moved from Heterocerus.

What's causing you to disagree with Boris's assessment?

The Heteroceridae have been reorganized, renamed.
A lot of new genus names have been applied. In any case, Heterocerus seems to no longer be in use. Since bugguide editors have elected to follow the taxonomy in American Beetles except for more recent and broadly accepted revisions, a new genus name will have to be given to this one. I expect Kerry Katz, who authored the American Beetles section on Heteroceridae, will help us straighten this out. I have recently sent him a batch of specimens (not this one obviously) and expect to hear back from him soon.

In the case of this particular image, I think I may have moved it out of the old genus when I moved several of mine. Trouble is, I don't know to which new genus this one has been assigned. We'll find out soon though.
