drugstore beetle damage-artwork

When drugstore beetles (Stegobium paniceum) infest an artwork, they tend to attack the middle support layer, feeding on the glue paste that adheres the supportive canvas lining to the back of the original painting. Externally visible damage can include exit holes where adult beetles emerge through the gummed brown paper tape that seals the sides of the artwork (A) and cracks in the paint layer (B) due to damage to the canvas underneath.
