    Hello, this strange mass of ‘cocoons’ was passed onto to me. It was found inside a bird box and was hard to remove. A larvae/caterpillar appeared. Does anyone know what it is? 

    Thanks.

    I had the same thing in a bird box in the garden a few years back. Incredible strength for a mass of cocoons, I had to virtually wrench the lid off!
