Lepidoptera The Large Emerald Moth – Geometra Papilionaria

The Large Emerald Moths Fig. 181.-The Large Emerald.

This species is the largest of the family, and measures over two inches when its wings are expanded. The colour is dull green, with whitish bands and spots, the arrangement of which may be seen in our engraving.

The moth is out in July, and is common in most parts of England.

The caterpillar feeds on birch (Betula alba), beech (Fagus sylvatica) and hazel (Corylus avellana) in the autumn, and hybernates while still young. In the spring it feeds again, and is full grown in June, when it changes to a chrysalis in a cocoon spun between leaves.
