Pebble Hook-tip

Drepana falcataria

Largest & commonest of the Hook-tips in Britain, mainly nocturnal.

Larvae feed on Birch, sometimes Alder.

The ground colour is light brown or white brown to reddish brown. The forewings, which exhibit a fine regular pattern of dark, finely serrated lines have a dark patch in the middle.

From the wing tip, a clearly curved, dark brown band runs under the stain up to the edge of the wing.

The hindwings are also light brown, but brighter than the forewings.

Their pattern is similar to but not so strong as that of the forewings.

In the Females the hindwings are white with the same dark patterning.

Flight period is from May-June & a 2nd brood in August.
