A Moth Invasion

This is tree in a small forest in southern Germany; it was completely covered by silk of ermine moths. At first glance it looks terrible but it’s also fascinating to the mass of caterpillars in the communal web. For the tree, the moths are highly dangerous. This one has lost all leaves.

The high amount of moths is also attractive for parasites; these are some ichneumon wasps placing eggs in the moth pupae.

  1. How interesting. I have seen this mass covering only once when it resulted in huge exploitation by many birds to feed on the millions of insects.

  2. We have those here all over the place. They do so much damage and you cannot get rid of them. One year I did see all the goings on within the web, and it was fascinating. Very prolific. You captures are so interesting.

  4. We used to have something like these at our home in Oregon (before we sold out when we retired)...people called them tent caterpillars -- and they were so destructive. Very interesting picture set!
