You may want to have a look at the files that are in the
"Bugs-r-Us" folder at http://groups.yahoo.com/group/SB-r-us/files/
One of them is a file entitled:
Bugs in Wet Conditions.pdf
Bugs that occur in building materials with elevated moisture levels
and it will contain line drawings and IIRC, some photos, as well as
descriptions of the conditions that create habitat for a number of bugs
that are likely to be found in wet straw.

Generally-speaking , there are often elevated moisture levels in the straw
during the first year or so following plastering operations, as a result
of moisture from the wet-applied plaster migrating into the straw and that
high humidity and warm temperatures within the straw create the conditions
which are amenable to numerous small insects.
As the walls dry out and if no further moisture loading occurs (ie
rain-wetted plaster, leaks) then suitable habitat for the insects will
cease to exist and as a result so will they.
This phenomenon of elevated moisture levels during the first year of
occupancy of new buildings is not unique to buildings with straw in the
walls nor is the presence of tiny insects.
In fact the presence of such insects is sp common that one of the
colloquial names for one such insect is "Plaster beetle".
One that seems to be common in SB buildings is mild climates like that of
Europe are Psocids (order Psocoptera).
