Common Bagworm Moth, Heesch, Netherlands
As the name suggests, highly common, in fact the most common bagworm in the Netherlands. Still, I was thrilled to find it. In particular because the 1:1 macro lens I use in the field is a little short in magnification for this topic.
I found it whilst peeking into my little pond in the garden, where in the corner of my eye I saw a little twig moving on its own on the garden floor. Subject size of the inner case is 8-12mm, yet individual building material may sometimes extend the total outside length.
I only carefully pinned a twig that was part of the case, not the larvae itself. It's unharmed and released.
