my guess is the larvae belong to a different species

Moved from Beetles.

 
Thanks, Blaine!
We would never have found this otherwise.

Did a bit of folow-up on the web on Ischalia larvae and found this article:

Daniel K. Young
The Coleopterists Bulletin
Vol. 39, No. 3 (Sep., 1985), pp. 201-206
"Description of the larva of Ischalia vancouverensis"
where he describes adults and larvae being found together feeding on fungal growth on decaying logs which was the case here. Larvae were subsequently raised.

I don't have the technical knowledge to follow all of the detailed description of the larvae in the article, but it seems very similar as does the illustration.
