Yes, Tom, so have I. Silverfish can also be found in hot attics.
It's interesting that there are uses for sericin after degumming.

[66] 

 [67]Silk moth pupae/cocoons are boiled in water and the cocoon
silk removed. The bare pupa is eaten (tastes O.K.)-- can quickly cook
with oil, spices. The hot water must aid in sericin removal or some
other process is also used? Raw silk fabric possibly prepared a
different way or sericin is removed via another method that doesn't
disturb it in boiling water? It is hot water soluble, however. Article
notes that it offers UV protection. If it's removed, then I guess the UV
protection goes out the window. But how about raw silk-- is UV
protection by virtue of leaving sericin intact?

Whitney, that's why I spoke about the natural situation whereby tineid

natural locations act as reservoirs for potential infestations in
collections in buildings.

>> FYI,
When silk is processed, the sericin layers on the outside of the fibroin
strands are usually removed (except in the case of "raw" silk). The
process is called "degumming." Fibroin is composed of the amino acids
serine, alanine, and glycine.

>> This is
a definition of silk from one publication: 
>> "Sericin is a hot
water-soluble macromolecular globular protein. It represents a family of
proteins having molecular mass of 10 to 310 kDa. Sericin envelops the
fibroin fibre with successive sticky layers that help in the formation
of cocoon. Sericin contributes about 20-30% of the total cocoon weight.
The sericin protein is made of 18 amino acids most of which have
strongly polar side groups such as hydroxyl, carboxyl and amino groups."

>> I'd say that silk is a protein, but is not keratin containing.
Dermestids don't feed on silk, but possibly tineid caterpillars are able
to? Yes, it's true that both tineid and dermestid larvae will chew on
silks as Tom notes, especially if there are stains and residues that
must be "tasty". In a natural situation, in caterpillar silk mats and
spider webs or retreats, there can be parts of shed skins, dried insect
and arachnid corpses (including dried spider prey), and the like that
would constitute a good diet for foraging dermestid and tineid larvae.

Neither dermestids nor clothes moth larvae eat silk. Silk has no keratin
(animal protein) in it. The text books are wrong. If dermestids or
clothes moth larvae damage silk, they inadvertently do so as they graze
on the sizing. Silk threads are so fine, the larvae may damage them, but
they are not "feeding" on the silken threads. They simply chew through
them as they forage of the sizing. Wool, horse hair, whale baleen,
porcupine quills, embroidery, etc. all have keratin and will support
fabric pest larval development.

Hello all,

of spiderwebs in one of our furniture storage areas and, upon cleaning
them up, found three dead beetles and a live (!) larva. I am fairly new

insight you might be able to share.
