A brief and very readable 1916 account of the life history of X. tabaniformis ssp. orpifex
, cited in Hurd(1)
and other references, can be found at this link
A moth referred to the old family "Phycitidae"—presumably now subsumed in the tribe Phycitinae
of current family Pyralidae.
In light of the descriptions of the feeding habits of Phycitinae on page 188 of Powell & Opler(2)
, and those of tenebrionids on page 213 of Evans & Hogue(3)
, the moth and beetle may be nest inquilines rather than true parasites of X. t. orpifex
