Common furniture beetle (anobium punctatum)
Generally known as woodworm, this insect attacks paper and cardboard, making circular holes, similar to those it makes in wood.

How to detect the insects that are eating your book collection
In order to conveniently detect any infestation scenario, it is necessary to know what the organisms feed on, where they shelter and what is the favorable environment for their presence and proliferation.
The first step towards the early detection of the presence of insects is the continuous monitoring of spaces and collections, namely through the use of traps.
The amount of insects that are trapped in the traps helps, not to eradicate them, but to understand if you are facing a pest or not. It is often thanks to these traps that the existence of problems in the building that are contributing to the increased presence of insects is indirectly detected.
