Euproctis chrysorrhoea - Hibernating cocoon
The young caterpillars of Euproctis chrysorrhoea collectively spin a cocoon in the tip of a twig of the host plant to spend winter hibernating. On Schiermonnikoog we saw many, many of these cocoons on Sea buckthorn, so I pulled a bit of the tissue aside to have a look at one of the small caterpillars inside:

The brown-tail is a moth of the family Lymantriidae. It is distributed throughout Europe. It is found in North America only on the coast of Maine and Cape Cod where it is considered an invasive species that arrived in the U.S. in the 1890s on nursery stock coming from Europe.

I did expect to find caterpillers in it, but somehow had a fantasy about one big one in my head, not dozens of tiny ones in each cocoon, so that _was_ a surprise :o) Posted 4 years ago
