23. May: A furry bunch of brown...
A furry bunch of brown hairy caterpillars is a typical find in coastal saltmarshes at the end of may. These are the caterpillar nests of the thermophilic Ground lackey moth. Only about 20 years ago this specis has reached the Waddensea coast - possibly arriving from english salt marshes. The caterpillars spend their first weeks sociably on a commonly spun silk carpet. They feed on different herbs like Sea aster, Sea arrowgrass or Sea plantain. The older caterpillars live individually and tend to develop blueish markings. The adult moths fly in july and leave egg clusters on plant stalks, from which new caterpillars hatch in next spring.
