Thrips are notorious for squeezing into glass-framed objects. They have evolved morphology and behavior to enable them to wriggle into leaf sheaths and unopened buds. If plants are unavailable, they will make do with picture frames, etc. These are almost certainly one of the cereal-feeding species, which often occur in vast numbers, and travel some distance on wind currents. They do not pose a threat to the objects. The frass you have found in the wooden frames will be from a different insect. Tunnels filled with sawdust-like frass suggest furniture beetles (*Anobium *sp.), and the silken material cases suggest moth larvae, which would explain the damage to the embroidery thread. Tony
