Ciidae, larva on shelf fungi Trametes elegans

Ciidae, larva on shelf fungi Trametes elegans
100 Acre Wood, Winneshiek County, Iowa, USA
July 3, 2010
More images of a similar larva taken 2 days later; July 5, 2010

1-Jul-10: shelf fungi Trametes elegans collected.
9-Sep-2010: broke open fungi and found lots of adult beetles.
8-Oct-2010: adult beetles collected,
several Neomida bicornis
and 2 Cis fuscipes
Cristiano Lopes-Andrade says: "The larva is certainly not a Ciidae. There are Erotylidae and Tenebrionidae larvae similar to that…"

possibly Ciidae
certainly on of the tenebrionoides. If not the Neomida bicornis you posted, then my guess is a ciid, possibly that undescribed adventive Octotemnus.

I think you've got it.
I was going on the assumption that this was the larva of the
Neomida bicornis (same fungi, weeks apart) but then saw
and that’s not this.

However, I did collect adults of another beetle in this fungi (at the same time as I collected the Neomida bicornis) and they look very much like Ciidae (which is a new family to me).

I have a heck of a time with rearing larvae on both fungi and composits. Both are home/food to more than I think. And I don't know how to resolve this: to find all the larvae utilizing a given fungi would be to destroy the fungi.

larva and allometric growth
Based on the size of the head in the larva you have photographed, it does not look like a mature larva anyway, so further ID might be difficult. I still have my mind set on Ciidae, but I don't have a tone of experience with larvae.

Possibly not a Ciidae larva
That seems not to be a ciid larva. Would it be possible to take a close up pic of the dorsal view of its head? So I can at least confirm whether that's a ciid or not.

Thanks
