Notodontidae » Notodontinae


42-50 mm.


Notodonta dromedarius has grey or dark brown forewings with rusty and yellowish stains. A broken rust-brown band runs along the outside edge of the front wing. There is a small discal spot, a postmedial crossline which is often broken and outer margins which are suffused dark red. The hindwings are usually pale grey-brown with dark veining. Specimens from the more northern parts of its range tend to be darker, with less orange and yellow. The greenish caterpillar, in common with many of the 'prominents', has several humps on the back. It lives mainly on birch (Betula).
