These tiny little creatures are feeding and molting and feeding and molting ...
During this process I can follow how they make "insect granulate" from wasps, spiders, moths, and the others. More species and ages are shown in this section from the Dermestidae family.
(Anthrenus verbasci, Anthrenus scrophulariae, Anthrenus museorum and others)
The disturbed larva roughs up it's hairs.
Mouth parts
Unfortunately the picture can't show properly, but these larvas let me see the inside structures of other insects. Below there is an antennae.
Leg parts
A half mouth part of a moth
Spider
They make some entrance, then they tend to eat from inside to outside.
They molt several times.
Then you see the "granulates" everywhere.
At the end, the miracle happens.
