17 I found a caterpillar on the dry fungus which was growing on birch near Thorndon Country Park (TQ 616913). The larva was obviously feeding on the fungus as its droppings were black. After a few days in captivity it pupated in a white cocoon and later emerged as a rather drab, brown micro, on the 5th November 1979. This moth was kindly identified by Col. A.M. Emmet. I would be interested to hear if anyone comes across this moth in other parts of Essex. Ian M Clenaghan References; 1. G. Kibby, "Mushrooms and Toadstools." Oxford University Press, p 250. 251. ,2.
